(a)

Interpretation Introduction

Interpretation:

Using Le Chatelier’s principle the effect of the following changes on the extent of hydrolysis of sodium nitrite (NaNO2) solution has to be predicted.

(a) HCl is added

(b) NaOH is added

(c) NaCl is added

(d) The solution is diluted

Concept Information:

Weak acid:

Weak acids ionize only to limited extent in water. At equilibrium, an aqueous solution of a weak acid has a mixture of unionized acid molecules, hhydronium ions and corresponding conjugate base.

Le Chatelier’s Principle:

This principle states that “at equilibrium, when any system is subjected to change in temperature, volume, pressure or concentration, then the system adjusts itself to counteract the effect of the applied change by establishing a new equilibrium”

To Predict: The effect of change on the extent of hydrolysis of sodium nitrite (NaNO2) solution on the addition of HCl
