Detailed Solution

The hydrolysis of FeCl₃ can be intensified by adding a strong base or a weak acid.

Out of the given reagents, option (a) NaOH and Na₂CO₃ both are bases and can intensify hydrolysis of FeCl₃.

Option (b) NH₄Cl and HCl are both acids, and HCl is a strong acid that can compete with the hydrolysis of FeCl₃. Therefore, option (b) cannot intensify the hydrolysis of FeCl₃.

Option (c) Na₂CO₃ is a base that can intensify the hydrolysis of FeCl₃, but adding NaOH and HCl together may neutralize each other's effects and not increase the hydrolysis of FeCl₃. Therefore, option (c) may or may not intensify the hydrolysis of FeCl₃.

Option (d) NH₄Cl is an acid that cannot intensify the hydrolysis of FeCl₃, while HCl and ZnCl₂ are both strong acids that can compete with the hydrolysis of FeCl₃. Therefore, option (d) cannot intensify the hydrolysis of FeCl₃.

Therefore, the correct answer is option (a) NaOH and Na₂CO₃.
