Question

In a saturated solution of barium chloride, the
concentration of chloride ions is double by adding
conc. HCI. This will cause the concentration of
barium ions​

Answer 1

Answer:

to decrease due to common ion effect

Answer 2

Answer:

apply LeChatlier’s Principle

On increasing the concentration of Cl- ions, The concentration of Ba2+ decreases

as Cl- ions will combine with Ba2+ to form BaCl2

To maintain their equilibrium constant K

some imp points

If conc... of any ion or molecule is increased then reaction move in the direction opposite to it

and if the Concentration of any ion is decreased the reaction move towards it...

To maintain the equilibrium constant .....( in both the case)

Because always if any system shows equilibrium condition then it definitely maintain its equilibrium constant..

Equilibrium constant can only be changed by the temperature....

{The above points are nothing but the LeChatlier’s principle}

I hope it helps you......
