What occurs when Na2SO4(s) is added to this system, increasing the concentration of SO42-(aq)?
1.
The equilibrium shifts to the left, and the concentration of Ba2+(aq) decreases.
2.
The equilibrium shifts to the left, and the concentration of Ba2+ (aq) increases.
3
The equilibrium shifts to the right, and the concentration of Ba2+ (aq) decreases.
The equilibrium shifts to the right, and the concentration of Ba2+ (aq) increases.

Respuesta :

Answer:

1

It also moves to the left.

Explanation:

When Na₂SO₄ is added to the equilibrium system then the equilibrium shifts to the left, and the concentration of Ba²⁺(aq) decreases.

What is equilibrium law?

Equilibrium law states that if any external stress is applied at the equilibrium state of any reaction then reaction will shift towards that side where the stress gets reduced.

Given chemical reaction is:

BaSO₄ ⇄ Ba²⁺ + SO₄²⁻

If in this equilibrium state, we add Na₂SO₄ as a result of which it increases the concentration of sulfate ion and equilibrium will shift towards the left side to maintain the concentration.

Hence the equilibrium shifts to the left, and the concentration of Ba²⁺(aq) decreases.
