Sample Karnataka SSLC Science (KSEAB) Practice Questions

Try these sample questions to review concepts for the Karnataka SSLC Science (KSEAB) exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which of the following is a chemical change?
A.Melting of ice
B.Burning of magnesium ribbon
C.Breaking of glass
D.Dissolving sugar in water
Explanation: Burning magnesium forms magnesium oxide, a new substance, so it is a chemical change.
2A balanced chemical equation primarily obeys the:
A.Law of conservation of mass
B.Law of independent assortment
C.Boyle's law
D.Ohm's law
Explanation: Balancing keeps the same number of each atom on both sides, reflecting conservation of mass.
3The reaction 2H₂O → 2H₂ + O₂ (by electricity) is an example of:
A.Combination
B.Displacement
C.Decomposition
D.Double displacement
Explanation: Electrolysis splits water into hydrogen and oxygen—one reactant forming two products is decomposition.
4In Zn + CuSO₄ → ZnSO₄ + Cu, the brown deposit on zinc is:
A.Zinc sulphate
B.Copper metal
C.Sulphur
D.Zinc oxide
Explanation: Zinc displaces copper from copper sulphate solution; copper metal deposits as a brown coating.
5When iron nails are placed in copper sulphate solution, the solution turns:
A.Blue to greenish
B.Green to blue
C.Colourless to pink
D.Yellow to red
Explanation: Fe displaces Cu; FeSO₄ forms (greenish) as blue CuSO₄ is consumed.
6BaCl₂ + Na₂SO₄ → BaSO₄ + 2NaCl is an example of:
A.Combination
B.Decomposition
C.Double displacement (precipitation)
D.Displacement by a metal
Explanation: Ions exchange partners and BaSO₄ precipitates—classic double displacement.
7In the reaction 2Fe + 3Cl₂ → 2FeCl₃, iron is:
A.Reduced
B.Oxidised
C.Neither oxidised nor reduced
D.Only a catalyst
Explanation: Iron gains chlorine (oxidation state increases from 0 to +3), so iron is oxidised.
8Which equation is correctly balanced?
A.H₂ + O₂ → H₂O
B.2H₂ + O₂ → 2H₂O
C.H₂ + 2O₂ → 2H₂O
D.2H₂ + 2O₂ → 2H₂O
Explanation: 2H₂ + O₂ → 2H₂O has 4 H and 2 O atoms on each side.
9An acid turns blue litmus:
A.Red
B.Blue
C.Green
D.Colourless
Explanation: Acids turn blue litmus red; bases turn red litmus blue.
10The pH of a neutral solution at 25 °C is:
A.0
B.7
C.14
D.1
Explanation: At 25 °C, pure water and neutral solutions have pH 7.

About the Karnataka SSLC Science (KSEAB) Exam

Karnataka SSLC Science is the Class 10 public examination science paper under the Karnataka School Examination and Assessment Board (KSEAB). It assesses NCERT-aligned Class 10 Science: chemical reactions and equations; acids, bases and salts; metals and non-metals; carbon and its compounds; periodic classification; life processes; control and coordination; reproduction; heredity; light (reflection and refraction); the human eye and the colourful world; electricity; magnetic effects of electric current; sources of energy; our environment; and management of natural resources. The official assessment is a mixed objective + subjective paper commonly lasting about 3 hours 15 minutes, with English and Kannada media. Fees and exact blueprints are notified by KSEAB on kseab.karnataka.gov.in (model papers are also commonly available via related board portals such as kseeb.karnataka.gov.in). Pass marks are commonly described as about 33% per subject with aggregate rules. The 100 questions on this page are a free English-language multiple-choice study adaptation with explanations and calculation practice; they are not a full simulation of the official mixed paper.

Exam sponsor: Karnataka School Examination and Assessment Board (KSEAB). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

Official KSEAB SSLC Science is assessed as a mixed paper: objective-style items plus subjective short and long answers, commonly lasting about 3 hours 15 minutes. Content follows Karnataka SSLC Science / NCERT-aligned Class 10 Science across Physics (light, electricity, magnetic effects, sources of energy), Chemistry (chemical reactions, acids/bases/salts, metals and non-metals, carbon compounds, periodic classification), and Biology (life processes, control and coordination, reproduction, heredity, our environment, management of natural resources). English and Kannada media are typically available. Exact theory–internal/practical splits are as published by KSEAB for the year — confirm circulars on kseab.karnataka.gov.in. This practice bank is an English-language MCQ study adaptation for concept and calculation fluency — it does not simulate official attempt limits, subjective long answers, or internal assessment.

Karnataka SSLC Science (KSEAB): Suggested Study Strategy

1Practice official KSEAB model/sample Science papers under timed ~3 h 15 m conditions so you can switch from MCQ drills to written short and long answers.
2For Physics numericals, write the formula first (V = IR, P = VI, 1/v − 1/u = 1/f), then substitute SI units carefully.
3Balance chemical equations and memorize the reactivity series and pH of common substances with short daily drills.
4Draw and label life-process pathways, the reflex arc, and plant/animal hormone tables from memory.
5Build a formula sheet for electricity, lens/mirror formula, and magnification; revise it weekly before SSLC.
6Use English/Kannada textbooks as directed by your school; this free bank is an English MCQ adaptation only.
