BaSO4(s) ⇌ Ba^(2+)(aq) + SO4(aq)^(2-) state the effect of - a. Addition of Ba^(2+) ion.

Question

For the equilibrium.

BaSO_4(s) ⇌ Ba²⁺_(aq) + SO_-4(aq)²

state the effect of -

a. Addition of Ba²⁺ ion.

b. Removal of SO₄^2- ion

c. Addition of BaSO_4(s)

on the equilibrium.

Answer 1

a. Addition of Ba²⁺ ion will favour the reverse reaction, (that is, equilibrium shifts from right to left). This increases the amount of BaSO₄.

b. Removal of SO₄^2- ion ion will favour the forward reaction, (that is, equilibrium shifts from left to right). This decreases the amount of BaSO₄.

c. Addition of BaSO_4(s) will not affect the equilibrium as the equilibrium constant expression does not include pure solids.
