How to you write a balanced molecular equation, with phases, between the KHP and the titrant, NaOH?

Question

KHP=potassium hydrogen phthalate=KHC^8H^4O^4

Answer 1

KHC8H4O4 (aq) + NaOH (aq) --> NaKC8H4O4 (aq) + H2O (l)

some might write it as:

KHC8H4O4 (aq) + NaOH (aq) --> KNaC8H4O4 (aq) + H2O (l)
