Question

H₃PO₄ is a polyprotic acid with three acidic protons. Identify the products of the first acid dissociation of H₃PO₄ in water.

Answer 1

Answer:

H3PO4 is a polyprotic acid with three acidic protons. Identify the products of the second acid dissociation of H3PO4 in water. H2PO4 (aq) + H2O(1) = 0 0 3+ 1 2 3 4 5 5 6 7 00 9 0 + s (1) (g) (aq)

Answer 2

Answer:

$H_2PO_4^- and H_3O^+$

Explanation:

$H_3PO_4 {\longrightarrow} H_2PO_4^- + H_3O^+$

When an acid dissociates  $H^+$ is given out. So when $H_3PO_4$ dissociates $H^+$ is given out so when one proton is removed $H_2PO_4^-$ is formed. As the reaction is done in water medium the proton is accepted by the lone pairs of oxygen in water molecule to form hydronium ion $H_3O^+$.
