🤓 Based on our data, we think this question is relevant for Professor Reed's class at SUNY.

Solution: What is the solubility of M(OH) 2 in a 0.202 M solution of M(NO 3)2? Ksp = 9.05 x 10 -18

Problem

What is the solubility of M(OH) 2 in a 0.202 M solution of M(NO 3)2? Ksp = 9.05 x 10 -18

Solution

 M(OH) has a Ksp, which stands for the solubility product constant. That means that  M(OH) 2 is a solid and it will dissociate as follows

 M(OH)2(s)  M2+ + 2OH– {aq}

Anytime we deal with Ksp, we are dealing with an ICE chart. Remember, in ICE charts we ignore anything that is a solid or a liquid, meaning we will ignore M(OH) 2.
