# Problem: What is the value of Q when the solution contains 2.50?10?3M Mg2+ and 2.00?10?3M CO32? ?

###### FREE Expert Solution

To calculate the value of Q from the given concentrations:

The reaction quotient, Q, can be calculated like an equilibrium constant with the formula shown below:

$\overline{){\mathbf{Q}}{\mathbf{=}}\frac{\mathbf{products}}{\mathbf{reactants}}}$

*like in equilibrium expression solids are ignored
*the coefficient of the species in the balanced reaction will be their exponents in the equilibrium expression

Let's write the reaction as: MgCO3 (s) → Mg2+ (aq) + CO32- (aq)
