1. What is the conjugate acid of CN-

answer.

HCN

to determine the conjugate acid one must take the formula of the base,CN-, and add a proton (H+) to this formula

base formula (CN-) + one proton(H+) = HCN

The conjugate acid has one more H+ than its base.

1. What is the conjugate acid of H2PO4-

answer.

H3PO4

to determine the conjugate acid one must take the formula of the base,H2PO4-, and add a proton (H+) to this formula

base formula (H2PO4-) + one proton(H+) = H3PO4

The conjugate acid has one more H+ than its base.
