Question

How do the concentrations of Ag and SO₄²- change when more solid ag2so4 is added to the already saturated solution?

- ag increases and SO₄²
- decreases Ag and SO₄²
- both increase Ag and SO₄²
- remain the same Ag and SO₄²
- both decrease

Answer 1

The concentrations of Ag+ and SO4^2- ions will remain the same when more solid Ag2SO4 is added to a saturated solution because the solution is at equilibrium and its solute capacity cannot be exceeded under the same conditions.

Step-by-step explanation:

When more solid Ag2SO4 is added to an already saturated solution, the concentrations of Ag+ and SO42- ions will remain the same. This is because the solution has already reached its saturation point, meaning that it contains the maximum amount of dissolved solute that it can hold at a given temperature and pressure.

Adding more solid does not change this because the added solid will simply not dissolve. The system is at equilibrium, and the addition of more solid does not affect the concentrations of the dissolved ions unless outside factors like temperature or pressure change.
