Which three types of solid can be reacted in excess with an acid to prepare a salt solution?
A metal, an insoluble base or an insoluble carbonate.
What products form when a metal reacts with an acid?
A salt and hydrogen.
What products form when an insoluble base reacts with an acid?
A salt and water.
What products form when an insoluble carbonate reacts with an acid?
A salt, water and carbon dioxide.
When preparing a salt solution using an excess insoluble reactant, what indicates that the acid has been used up?
Some added solid remains unreacted.
How is excess solid removed from a salt solution?
By filtration.
How are salt crystals obtained from the filtrate after excess solid has been removed?
Evaporate some water, cool the filtrate to form crystals, then separate and dry them.
