Equivalent weight of H_(3) PO_(2) is ( M rarr molecular weight)

Find out the equivalent weight of H_(3) PO_(4) in the reaction: Ca(OH)_(2) + H_(3) PO_(4) rarr CaHPO_(4) + 2 H_(2) O

In H_(3)PO_(4) which of the following is true?

H_(4)underline(P_(2))O_(6)+H_(2)O to H_(3)PO_(3)+H_(3)PO_(4)

H_(4)underline(P_(2))O_(6)+H_(2)O to H_(3)PO_(3)+H_(3)PO_(4)

For H_(3)PO_(4) , H_(3)PO_(4) rarr H_(2)PO_(4)^(-)+H^(+)(K_(1)), H_(2)PO_(4)^- rarr HPO_(4)^(-)+H^(+) (K_2), HPO_(4)^(2-) rarr PO_(4)^(3-) + H^(+) (K_(3)) then

H_(4)underline(P_(2))O_()+H_(2)O to H_(3)PO_(3)

H_(4)underline(P_(2))O_()+H_(2)O to H_(3)PO_(3)

H_(4)underline(P_(2))O_(7)+H_(2)O to 2H_(3)PO_(4)

H_(4)underline(P_(2))O_(7)+H_(2)O to 2H_(3)PO_(4)
