will strive to reach equilibrium. In an aqueous
mixture, both reaction are occurring

Answer 8

law of mass action

Question 9

solution obtained by dissolving the maximum amount of solute at a given temperature

Answer 9

saturated solution

Question 10

a solution that contains more amount of solute that the required to saturate

Answer 10

supersaturated

Question 11

difference between saturated and supersaturated solution

Answer 11

at a given temperature, saturated solution has a maximum amount of solutes in the solution

supersaturated solution has more than the maximum amount of solute in the solution
