Question

A buffer is made by dissolving H3PO4 and NaH2PO4 in water. a. write an equation that shows how this buffer neutralizes a small amount of acids. b. write an equation that shows how this buffer neutr?

Answer 1

H3PO4 ==> H^+ + H2PO4^2-

H2PO4^2- + H^+(small amount acid) = H3PO4.
Adding NaOH, it neutralizes by
H3PO4 + NaOH ==> NaH2PO4 + H2O OR
H3PO4 + OH^- ==> H2O + H2PO4^-

Answer 2

No
