Question

Question 7 of 31If a precipitation reaction occurs, what will be the products of the unbalancedreaction shown below?Mg(NO3)2(aq) + KOH(aq) →-Solubility TableA. No precipitate will form.B. KNO3(s) + Mg(OH)2(s)C. KNO3(s) + Mg(OH)2(aq)D. KNO3(aq) + Mg(OH)2(s)

Answer 1

According to the given information, the products formed from the reaction are

KNO3 and Mg(OH)2.

KNO3 is a salt that is soluble in water.

Mg(OH)2 is an hydroxide that is not soluble in water.

It means that a precipitate of Mg(OH)2 will be formed in the reaction, then, the products of the reaction are:

KNO3(aq)+Mg(OH)2(s).

The correct answer is D.
