Asked by wiki @ 04/12/2021 in Chemistry viewed by 428 People

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

Answered by wiki @ 04/12/2021

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
