Strong & Weak Acids & Bases

A strong acid is an acid which is totally ionised in aqueous solution forming hydrate hydrogen
ions, H3O+

A weak acid is an acid that is…

H2O + H2O H3O + + OH-

I onic product of water (kw) = [H +][OH - ]

pH Scales

pH =- log[H +]

[H +] = e-pH

pKw, pOH & pKa

p means `the negative log of'

pK w =- logK w K w = pH + pOH =…

The pH of weak acids can be calculated in the same way as the acid dissociation constant.
[H3O+][A-]
acid dissociation constant (ka) = [HA]


You would use the concentration at equilibrium.

Diprotic acids would produce two hydrogen ions per molecule e.g. sulphuric acid.

pH of Weak Bases

The pH of…
