An acid is a source of...
hydrOGEN ions (H+)
A base is...
a substance which can neutralise an acid. Alkalis are soluble bases.
An alkali is a source of...
hydrOXIDE ions (OH-)
The reaction between and acid and a base:
acid + base --> salt + water
or, H+(aq) + OH-(aq) --> H2O
The products are neutral.
What is the name of the reaction between and acid and a base?
Reaction between acids and metal oxides or metal hydroxides
Metal oxides/hydroxides are usually bases so they react the same way.
acid + metal oxide/hydroxide --> salt + water
The salt produced is determined by the acid used:
sulfuric acid + copper oxide --> copper sulfate + water
Reaction between acids and metal carbonates
acids + metal carbonate --> salt + water + carbon dioxide
The salt you get depends on the acid you used:
hydrochloric acid + sodium carbonate --> sodium chloride + water + carbon dioxide
