  2. BThe acidity of N H 4 + is enhanced in the presence of C u 2 +
  3. CThe acidity of H 3 B O 3 is increased in the presence of glycerol
  4. DAll of the given are examples of cosolvating effect

Correct answer

D. All of the given are examples of cosolvating effect

Step-by-step solution

cosolvating effect is a substance added to primary solvent in small amount in order to increase solubility of partialy soluble compounds. Here all statements are correct based on cosolvating effect.
