Phosphoric Acid and Sodium Hydroxide (First Neutralization)

H3PO4 + NaOH → NaH2PO4 + H2O

अवलोकन

The first neutralization step of the triprotic phosphoric acid produces monosodium phosphate and water. Phosphoric acid has three ionizable protons with Ka1 = 7.1 × 10⁻³, Ka2 = 6.3 × 10⁻⁸, and Ka3 = 4.2 × 10⁻¹³. Each successive proton is progressively harder to remove.
