Explanation:
There are quite a number of ways to increase the solubility of substances.
Solution is a homogeneous mixture formed by dissolving a solute in a solvent.
Here are some things that can increase the rate of dissolution;
- Grinding/pulverizing - helps to increase the surface area for the solvent to react.
- Stirring - to bring more solvent in contact with the solute intimately.
- Heating - to facilitate dissolution of solute in solvents.

Explanation:
The nomenclature of ionic compounds is given by:
1. Positive is written first. And if the metal atom has various oxidation states then its oxidation state is to be mentioned in brackets with help of roman numbers
2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.
1.) : Calcium chloride (Correct)
In the given compound, calcium has oxidation state of +2 and chlorine has oxidation state of -1.The name is correct.
2.) : Copper (II) oxide (Incorrect)
In the given compound,copper has the oxidation state of +1 and oxygen has oxidation state of -2.So ,the correct name will be Copper (I) oxide.
3.) : Lead (II) sulfide (Incorrect)
In the given compound, lead has the oxidation state of +4 and sulfur has oxidation state of -2. So ,the correct name will be Lead (IV) sulfide.
