Which of the following statements regarding electrolysis of brine (aqueous solution of sodium chloride) is correct?
सही उत्तर: क) Chlorine gas is produced at the cathode and hydrogen gas is produced at the anode.
During electrolysis of brine, chlorine (Cl⁻) gains electrons at the cathode, forming Cl₂ gas. Simultaneously, sodium ions (Na⁺) are reduced at the cathode to form sodium metal. Chloride ions (Cl⁻) are oxidized at the anode, forming oxygen gas (O₂) and hydrogen gas (H₂). The other options describe incorrect processes that occur during the electrolysis of brine.

What volume of 0.5 M solution can be prepared by dissolving 28 grams of anhydrous sodium carbonate (Na₂CO₃) in water?
सही उत्तर: घ) 1000 mL
First, calculate the molar mass of Na₂CO₃: 2(22.99) + 10.6 + 3(16) = 105.99 g/mol. Then, determine the number of moles: 28 / 105.99 ≈ 0.264 moles. Use the formula Molarity = moles / volume to solve for volume: Volume = moles / Molarity = 0.264 / 0.5 = 0.528 L = 528 mL, which is closest to 500mL. The other options are incorrect as they are based on calculations with incorrect molar amounts.

The percentage by mass of chlorine in potassium chlorate, KClO₄, is approximately what?
सही उत्तर: ख) 29%
First calculate the molar mass of KClO₄: 39.1 (K) + 35.5 (Cl) + 4(16) = 122.6 g/mol. Then, calculate the mass of chlorine in one mole of KClO₄: 35.5 g. Finally, find the percentage by mass: (35.5 / 122.6) * 100% ≈ 29%. The other options are incorrect because they result from calculations based on different molar masses or using an incorrect chlorine mass.

What volume of 6 M H₂SO₄ solution is required to neutralize 50 mL of 3 M NaOH solution?
सही उत्तर: क) 10 mL
The neutralization reaction between H₂SO₄ and NaOH is a 1:1 molar ratio. Therefore, we use the formula: M₁V₁ = M₂V₂. Plugging in the values: (6)(V₁) = (3)(50). Solving for V₁, we get V₁ = 25 mL. The other options are incorrect because they don't follow the correct stoichiometric calculation.
