C) Cu3 (PO4)2. of Services, Solubility in Chemistry: Definition & Properties, Working Scholars Bringing Tuition-Free College to the Community. 1 g = 1 ml Hydrogens can only dissociate from the COO-H bonds. a) (NH4)2S c) the net ionic equation. According to the soubility table, Ba2+ is not very soluble and therefore makes the precipitate. Dissociation is complete as shown in the equation.

The equation for K3PO4 is:H3PO4 + KOH = K3PO4 + H2OIt is also useful to have memorized the common strong acids and bases to determine whether K3PO4 acts as an acid or base in water (or if it forms a neutral solution).Strong acids: HCl, H2SO4, HNO3, HBr, HI, HClO4Weak acids: HF, CH3COOH, H2CO3, H3PO4, HNO2, H2SO3Strong Bases: LiOH, NaOH, KOH, Ca(OH)2, Sr(OH)2, Ba(OH)2Weak Bases: NH3, NH4OHNote that we are talking about whether K3PO4 is an acid, base, or neutral when dissolved in water.- Salts of strong bases and strong acids: pH will remain neutral at 7.- Salts of weak bases and strong acids: pH less than 7 (acidic).- Salts from strong bases and weak acids: pH greater than 7 (alkaline).Based on these rules, the solution of K3PO4 dissolved in water is Basic.For polyprotic acids (e.g.
