Calculating the pH of bases requires an extra step, as they dissociate with water to make hydroxide ions, OH - , instead of hydronium ions, ...

The hydronium ion concentration, [H 3 O + ], can be used to determine the pH of a solution: pH = - log [H 3 O + ] For example: The pH of a ...

POLYPROTIC ACIDS Most of the acids we work with can only donate one proton (H + ion). However, some acids have more than one hydrogen ion t...

When an acid and a base react, we call it a neutralisation reaction. The products are water and a salt. Until now, we have looked at strong ...
