After 50.0 ml of a 0.100 m solution of naoh is added to 50.0 ml of a 0.100 m solution of an unknown acid, the equilibrium ph is basic. what may be concluded about the identity of the acid?

Respuesta :

It is concluded that the identity of the acid must be a weak acid, but it could be either monoprotic, diprotic, or polyprotic.

Reaction :

It is the titration of a weak acid and a strong base.

It is a neutralisation reaction of monobasic acid and monoacidic base (sodium hydroxide).

The determination of a weak acid in a titration is based on its molar mass and pKa (from points on a titration curve), and its approximate melting point.

The relationship between normality and molarity is :

Normality = base acidity x acid molarity.

We can use M1V1 = M2V2.
