First you need to write the dissociation reaction of the acid. Considering it is a mono protic weak acid , then you should know the degree of dissociation of this acid and it's concentration.
Then referring to the attached figure, H+= c*a
where a is degree of dissociation and c is the concentration of acid.
If it's a di protic acid, then it will have two dissociation constant and two different degree of dissociation, then
H+ = c*a1 + c*a2
where a1 and a2 are degrees of dissociation
Then referring to the attached figure, H+= c*a
where a is degree of dissociation and c is the concentration of acid.
If it's a di protic acid, then it will have two dissociation constant and two different degree of dissociation, then
H+ = c*a1 + c*a2
where a1 and a2 are degrees of dissociation
