Question

state the formula of the conjugate base of H3O+​

Answer 1

Answer:

Explanation:

to form its conjugate base

an acid donate a proton to form its conjugate base

H30  ⇌ H + H20

THEREFORE THE CONJUGATE BASE OF H30 IS H20

Answer 2

i think it is incomplete so,

H3PO4 + H2O ==> H3O^+ + H2PO4^-

So H3PO4, phosphoric acid, lost a proton to form H2PO4^- so H2PO4^- is the conjugate base of H3PO4, the acid. H3PO4/H2PO4^- is the acid/conjugate base pair. H2O gained a proton to form H3O^+; therefore, H2O is the base and H3O^+ is its conjugate acid. The H2PO4^- ion is named dihydrogen phosphate ion.
