Will a precipitate form when 100.0 mL of a 7.5 10-4 M Mg(NO3)2 is added to 100.0 mL of 5.8 10-4 M NaOH? (Hint: Ksp for Mg(OH)2 = 8.9 10-12)
Give the value of Q, to support your answer.
1 answer
Calculate the M of Mg ion and NaOH and solve for Qsp. If Qsp exceeds Ksp it will ppt. If not it will not ppt.
