Borax is a white crystalline solid and it is_________________?
Correct answer: B. More soluble in hot water
- A. More soluble in cold water
- B. More soluble in hot water
- C. Insoluble in water
- D. Soluble only in organic solvents
Explanation
Borax dissolves more readily as temperature increases, so it is more soluble in hot water than in cold water. The likely mistake is choosing insoluble in water because borax is a crystalline solid, but its ionic nature allows it to dissolve in water.

About Reactions of Group IV Elements
Group IV, or Group 14, chemistry covers the trends from carbon and silicon to tin and lead, including their reactions with oxygen, halogens, water, acids and alkalis. It also examines the structures and properties of their oxides and chlorides, oxidation states, and the inert pair effect, rather than treating all members as equally metallic.
