Question

When 12.0 mL of a 2.43×10* M magnesium nitrate solution is combined with 15.0 mL of a 5.89×104 M potassium hydroxide
solution does a precipitate form?
(yes or no)
For these conditions the Reaction Quotient, Q, is equal to

Expert Solution

Step 1

Ans

Concentration of Mg²⁺ after mixing the solution = 2.43×10^-4 M/(27ml/12ml)=1.08 ×10^-^{4 M}

Concentration of OH- after mixing the solution = (5.9×10^-4 M/(27/15ml) = 3.3×10^-4 M
