The following equilibrium exists in aqueous solution `CH _(3) COOH hArr CH _(3) COO ^(-) + H ^(+)` If dil HCl is added without change in temperature, the

A

concentration of `CH_(3) COO^(-)` will increase.

B

concentration of `CH _(3) COO^(-)` will decrease.

C

the equilibrium constant will increase.

D

the equilibrium constant will ạecrease.

Text Solution

Verified by Experts

The correct Answer is:
B
`CH _(3) COOH hArr CH _(3) COO ^(-) + H ^(+)`
If dil. HCL is added to the above equilibriu, due to the common ion effect the concentratio of `CH _(3) COO ^(-)` decreases.
