Q:

Which of the following is not soluble in water?

A) copper(II) hydroxide B) sodium chloride
C) silver nitrate D) potassium sulfate
 
Answer & Explanation Answer: A) copper(II) hydroxide

Explanation:

Sodium chloride:

The solubility rules tell you that all halides are soluble with the exception of those formed with siver, mercury, and lead ions. Since this is not the case here, sodium chloride will be soluble.

 

Silver nitrate:

It is soluble because all nitrates are soluble, without exception.

 

Potassium sulfate:

It is soluble because all sulfates are soluble with the exception of those formed with silver, calcium, barium, mercury, lead, and strontium ions.

 

Copper (II) hydroxyde:

It is insoluble because all hydroxides are insoluble with the exception of those formed with alkali metal ions and barium.
