Acid-Base IndicatorsFor each indicator, the change from dominating acid from to dominating base form occurs in a narrow range of approximately two pH units. Strong acids are not electrolytes. First we need to figure out the acid and base that were neutralized to form Potassium phosphate. For the reaction K 3 P(s) + 2 O 2 (g) K 3 PO 4 (s), we can see that water isn't formed, which means this isn't an acid-base reaction. Carboxylic acids do not dimerise in water, but forms hydrogen bonds with water. 0 mL H2SO4 solution is. Is k3po4 acidic or basic? Top Answer. In this case an acid and a base are neutralized. 009575 mol KOH x 1 mol H 3 PO 4 /3 mol KOH = 0. CaCl2, salt -- does not hydrolyze, neutral.
