The grams of NaH 2 PO 4 needed to react with 43.74 mL of 0.285 M NaOH is to be calculated. Concept introduction: Strong acids and strong bases are the substance that dissociates completely into its ions when dissolved in the solution. They dissociate completely in water to release H + ions and OH − ions. Weak acids and weak bases are the substance that does not dissociate completely into its ions when dissolved in the solution. They dissociate partially in water to release H + ions and OH − ions. Sodium dihydrogen phosphate ( NaH 2 PO 4 ) is a weak acid and sodium hydroxide ( NaOH ) is a strong base. Sodium hydroxide ( NaOH ) dissociates completely into ions and sodium dihydrogen phosphate ( NaH 2 PO 4 ) dissociates to some extent into ions. They both react to form sodium phosphate and a water molecule. The molecular equation for the acid-base reaction of sodium dihydrogen phosphate and sodium hydroxide is: NaH 2 PO 4 ( s ) + 2 NaOH ( a q ) → Na 3 PO 4 ( a q ) + 2 H 2 O ( l )
