Question

The solubility level of an aqueous solution of NaCl at 25°C is:

• A. 20g
• B. 36g
• C. 95g
• D. 8g

Hint:

Solubility is the maximum amount of solute that can dissolve in a solvent at a given temperature, which for NaCl at 25°C is 36g per 100g of water.

Answer 1

The Correct Option is B

The solubility level of an aqueous solution of NaCl at 25°C is: 

• Option 1: 20g - This is lower than the actual solubility of NaCl at 25°C.
• Option 2: 36g - This is the correct answer. Sodium chloride (NaCl) has a solubility of approximately 36 grams in 100 milliliters of water at 25°C.
• Option 3: 95g - This is too high for the solubility of NaCl at 25°C. NaCl does not dissolve at this high concentration in water at this temperature.
• Option 4: 8g - This is far too low for the solubility of NaCl in water at 25°C.

Explanation:

The solubility of NaCl (sodium chloride) in water at 25°C is approximately 36g per 100mL of water. This is the correct answer as it reflects the typical solubility of NaCl under normal conditions at this temperature.
