We´re asked to determine the value of Q for a solution made of Mg2+ cation and CO32- anion.
The reaction quotient Q is used to determine if our chemical reaction is at equilibrium. It’s a measurement of the ratio between products over reactants at a certain time, not only at equilibrium.
The reaction is the following:
MgCO3(s) ⇌ Mg2+(aq) + CO32-(aq)
What is the value of Q when the solution contains 2.50 x 10 -3 M Mg2+ and 2.00 x 10-3 M CO32-?
