Strong acids are those that ionizes almost completely in water. to be considered a strong acid, an acid must have an acid ionization constant ka > 55. the strong acid hcl in aqueous solution undergoes the ionization reaction: hcl (aq) + h2o (l) ⇋ h3o + (aq) + cl - (aq) and its ka = 2.00 x 106. if the concentrations of h3o + and cl - are both found to be equal to 0.153 mol/l what is the remaining concentration hcl that is not ionized

Ka is the equilibrium constant for the ionization for a reaction. It is calculated as follows

ka is equal to (H3o ions) (A-) divided by (HA)

2.00x106i s equal to 0.153x0.153 divided by (HA)

(2.00x106) HA is equal to 0.023409

HA concentration is therefore equal to 0.023409/2.00x106 which is 1.104x10^-4moles/litre
