# What is the normality of 0.3 M of H_3PO_4?

In spite of this, generally ${H}_{3} P {O}_{4}$ is considered an acid and its Normality is like the concentration of ${H}^{+}$ions if the compound is completely dissociated, hence it would be triple of molarity = 0,9 M
If you want titrate the acid you never titrate the third hydrogen atom but the first (with indicator orange Methyl) or the second (with indicator Phenolphtaleine) so in these reactions ${H}_{3} P {O}_{4}$ normality would be respectively 0,3 N and 0,6 N
