1In a school chemistry laboratory, which Globally Harmonized System (GHS) pictogram represents an oxidizing chemical that can cause or intensify combustion of other materials?
A.A flame over a circle
B.A plain flame without a circle
C.A skull and crossbones
D.A corroding metal surface and hand
Explanation: The flame over a circle pictogram specifically identifies oxidizing solids, liquids, or gases under the GHS framework. Oxidizers release oxygen or readily accept electrons, thereby initiating or intensifying fires in combustible materials. Recognising this symbol is essential for separating oxidizers from organic solvents and flammable materials.
2A student needs to accurately deliver exactly 25.00 mL of standard sodium hydroxide solution into a conical flask for a titration. Which piece of laboratory glassware should be used?
A.A 50 mL graduated beaker
B.A 25 mL graduated measuring cylinder
C.A 25 mL volumetric pipette
D.A 100 mL conical flask
Explanation: A 25 mL volumetric (transfer) pipette is calibrated to deliver a single, highly precise volume of liquid (typically to ±0.03 mL at 20 °C). This high precision is required when dispensing aliquots of analyte or primary standard in quantitative volumetric analysis. Graduated cylinders and beakers lack the precision needed for analytical titrations.
3Consider the industrial synthesis of bromomethane via the reaction: CH4 + Br2 -> CH3Br + HBr. What is the percentage atom economy for the production of bromomethane? (Molar masses: C = 12.01 g/mol, H = 1.008 g/mol, Br = 79.90 g/mol; CH4 = 16.04 g/mol, Br2 = 159.80 g/mol, CH3Br = 94.94 g/mol, HBr = 80.91 g/mol)
A.54.0%
B.46.0%
C.73.2%
D.100%
Explanation: Atom economy is defined as (molar mass of desired product / total molar mass of all reactants) × 100%. Here, the molar mass of the desired product CH3Br is 94.94 g/mol, and the total mass of the reactants is 16.04 + 159.80 = 175.84 g/mol. Calculating (94.94 / 175.84) × 100% yields 54.0%, illustrating that substitution reactions inherently waste a significant fraction of reactant mass as by-products.
4Which of the following chemical manufacturing practices directly adheres to the green chemistry principle of using renewable feedstocks?
A.Cracking petroleum-derived naphtha to synthesize ethylene
B.Fermenting sugar cane molasses to produce bioethanol
C.Using metallurgical coke from coal as a reducing agent in blast furnaces
D.Steam reforming natural gas (methane) to generate hydrogen gas
Explanation: The principle of using renewable feedstocks emphasizes sourcing chemical raw materials from agricultural or biological processes that can be replenished rapidly, rather than depleting non-renewable geological reserves. Sugar cane molasses is an annually harvested agricultural by-product fermented to yield bioethanol. The other options all consume finite fossil fuel deposits.
5How does percentage yield fundamentally differ from percentage atom economy in industrial chemical manufacturing?
A.Percentage yield measures theoretical stoichiometric efficiency, whereas atom economy measures experimental laboratory efficiency
B.Percentage yield measures experimental conversion of reactants into recovered product, whereas atom economy measures the proportion of reactant atoms incorporated into the desired product
C.Percentage yield can never exceed 50%, whereas atom economy always equals 100%
D.Percentage yield evaluates chemical toxicity, whereas atom economy measures energy consumption in kilojoules
Explanation: Percentage yield is an experimental metric that compares the actual mass of product collected to the maximum theoretical mass predicted by stoichiometry: (actual mass / theoretical mass) × 100%. In contrast, atom economy is a theoretical measure based on the balanced equation that evaluates how efficiently reactant atoms are incorporated into the target molecule rather than waste by-products. A reaction can have a 100% yield while having a low atom economy if heavy by-products are formed.
6What is the correct and safe procedure for preparing a dilute solution of concentrated sulfuric acid in a secondary school chemistry laboratory?
A.Rapidly pour concentrated acid into water while keeping the container tightly sealed
B.Slowly add concentrated sulfuric acid to a large volume of water with continuous stirring
C.Slowly add water to concentrated sulfuric acid while chilling in an ice bath
D.Pour equal volumes of water and concentrated acid simultaneously into an empty beaker
Explanation: The hydration of concentrated sulfuric acid is intensely exothermic. Adding the dense acid slowly down the side of the container into a larger volume of water with stirring allows water's high heat capacity to dissipate the thermal energy safely. If water were added to concentrated acid, the less dense water would float on top, boil instantaneously, and splatter boiling concentrated acid onto the experimenter.
7In an acid-base titration, a student records an initial burette reading of 1.15 ± 0.05 mL and a final burette reading of 24.65 ± 0.05 mL. What is the titre volume delivered and its absolute uncertainty?
A.23.50 ± 0.05 mL
B.23.50 ± 0.10 mL
C.25.80 ± 0.10 mL
D.23.50 ± 0.00 mL
Explanation: The delivered titre is the difference between the final and initial readings: 24.65 - 1.15 = 23.50 mL. When subtracting two experimental measurements, their absolute uncertainties are summed: 0.05 mL + 0.05 mL = ±0.10 mL. Therefore, the properly reported measurement is 23.50 ± 0.10 mL.
8Which of the following compounds is universally suitable as a primary standard for standardizing aqueous sodium hydroxide solutions in volumetric analysis?
A.Anhydrous sodium hydroxide (NaOH)
B.Potassium hydrogen phthalate (KHC8H4O4)
C.Concentrated hydrochloric acid (HCl)
D.Hydrated copper(II) sulfate (CuSO4·5H2O)
Explanation: Potassium hydrogen phthalate (KHP) meets all essential criteria for an analytical primary standard: it can be obtained at extremely high purity (>99.9%), is non-hygroscopic and stable in air, has a high molar mass (204.22 g/mol) that minimizes relative weighing errors, and reacts cleanly with NaOH in a well-defined 1:1 stoichiometric ratio.
9In the industrial synthesis of ibuprofen, the classical Boots process required six stoichiometric steps and achieved an atom economy of approximately 40%, whereas the modern BHC catalytic process requires three steps and achieves an atom economy of 77%. What makes the BHC process superior according to green chemistry?
A.It generates toxic chlorinated waste that is easily diluted in open sea outfalls
B.It employs recyclable heterogeneous catalysts and incorporates almost all reactant atoms into the desired product or recoverable acetic acid
C.It replaces all water and organic solvents with compressed ozone
D.It relies on non-selective free-radical reactions that produce multiple branched isomers
Explanation: The BHC process exemplifies green chemistry by replacing stoichiometric metal hydrides and hazardous Friedel-Crafts reagents with recoverable heterogeneous catalysts (such as Raney nickel and palladium). By streamlining the synthesis to three catalytic steps, the atom economy increases from 40% to 77% (or 99% if the generated acetic acid is recovered), drastically reducing toxic chemical waste.
10A chemical container displays a GHS pictogram consisting of an exclamation mark inside a red diamond. What specific category of hazard is signaled by this pictogram?
A.Severe explosive blast hazard under friction or shock
B.Acute lower-level toxicity, skin irritation, or respiratory sensitization
C.Target organ carcinogenicity and germ cell mutagenicity
D.Severe irreversible corrosion of metal containers and human skin tissue
Explanation: The GHS exclamation mark pictogram indicates less severe health hazards, such as Category 4 acute oral/dermal/inhalation toxicity, skin and serious eye irritation, dermal sensitization, or specific target organ toxicity following single exposure (narcotic effects or respiratory irritation).
