Dear Readers,

Compared to other sections, Chemistry is considered to be the most scoring section. If prepared thoroughly, chemistry can help students to secure a meritorious position in the exam. These questions are very important in achieving your success in Exams after 12th.

Q1. An electrolyte

  •  Forms complexions in solution
  •  Gives ions only when electricity is passed
  •  Possesses ions even in solid state
  •  Gives ions only when dissolved in water

Possesses ions even in solid state

Q2. Electrolytes when dissolved in water dissociates into ions because

  •  They are unstable
  •  The water dissolves
  •  The force of repulsion
  •  The forces of water are broken down by water

The forces of water are broken down by water

Q3. Which of the following is non-electrolytes?

  •  NaCl
  •  CaCl2
  •  C12H22O11
  •  CH3COOH


Q4. Electrolyte can conduct electricity because

  •  Their molecules contain unpaired electrons, which are mobile
  •  Their molecules contain loosely held electrons which get free under the influence of voltage
  •  The molecules break up into ions when a voltage is applied
  •  The molecules are broken up into ions when the electrolyte is fused or is dissolved in the solvent

The molecules are broken up into ions when the electrolyte is fused or is dissolved in the solvent

Q5. The addition of a polar solvent to a solid electrolyte results in

  •  Polarization
  •  Association
  •  Ionisation
  •  Non-liberation of heat


Q6. Which of the following compounds will not undergo decomposition on passing electricity through aqueous solution?

  •  Sugar
  •  Sodium Chloride
  •  Sodium Bromide
  •  Sodium Acetate


Q7. The aqueous solution of which of the following decomposes on passing electric current

  •  Cane Sugar

  •  Methanol
  •  Potassium Iodide

Potassium Iodide

Q8. An electric current is passed through an aqueous solution of the following. Which one shall decompose?

  •  Urea
  •  Glucose
  •  AgNO
  •  Ethyl Alcohol


Q9. Electrolysis involves oxidation and reduction respectively at

  •  Anode and cathode
  •  Cathode and anode
  •  At both the electrodes
