Acids and Alkali
- Acids are substances which form H+(aq) ions when added to weater.They have a PH less than 7
- Alkalis are substances which form OH- (aq) ions when added to water. They are a base that dissolves in water.
this is the equation for any neutralisation reactions.
- acids+ alkali - salt + water
neutralisation in terms of ions looks like this:
- H+(aq) + OH-(aq) -H2O(l)
Base= a substance that will neutralise an acid ( includes all alkalis). It has a PH greater than 7.
