Reactions of acids

What does an acid and a metal react to make?

salt + hydrogen

What are acids neutralised by?

both alkalis and bases

What does an acid and akali make?

salt + water

what does an acid and base make?

salt + water

what does an acid and metal carbonate make?

salts, water and carbon dioxide

What salts do hydrochloric, nitric and sulfuric acids make?

HCL - Chlorides

Nitric - Nitrates

Sulfuric - Sulfates

What are soluble salts made from?

by reacting acids and insoluble substances

Briefly describe crystallisation

1) Add chose insoluble substance to the acid. (The solid will dissolve)

2) The acid has been neutralised when the excess solid hits the bottom.

3) Filter excess solid, leaving the salt solution, and evaporate.

What type of ions do acids produce?

Acids produce hydrogen ions (H+) in solution.

What type of ions do alkalis produce

Alkalis produce hydroxide ions (OH-) in solution.

What do strong acids do in aqueous solutions?

Strong acids completely dissociate into their ions, producing a high concentration of hydrogen ions (H+) in aqueous solutions.

What do weak acids do aqueous solutions?

Weak acids partially dissociate in solution, resulting in a lower concentration of hydrogen ions (H+) compared to strong acids.
