Question

Consider the equilibrium below:

AgCl(s) Ag1+(aq) + Cl1-(aq)

Ho = 66 kJ

Use LeChatelier's principle to predict the effect on the chloride ion concentration caused by each of the following actions:

Action	Effect on [Cl1-]
adding silver chloride	---Select--- increases unchanged decreases
adding silver ion	---Select--- increases unchanged decreases
adding water	---Select--- increases unchanged decreases
heating	---Select--- increases unchanged decreases

Answer 1

AgCl(s) <=> Ag+(aq) + Cl-(aq)

Adding silver chloride , No change

Adding silver ion , decrease

Adding water, molarity decreases so increment in chloride ion

Heating increases because reaction is endothermic
