WebSilver phosphate is less soluble in Na 3PO 4(aq) than in water. Why? Some insoluble compounds are amphoteric. The solubility of many salts is affected by the pH of the solution. The solubility of most salts increases as temperature increases. A common ion displaces the solubility equilibrium towards the undissolved solute. WebApr 30, 2024 · A salt that is derived from the reaction of a strong acid with a strong base forms a solution that has a pH of 7. An example is sodium chloride, formed from the neutralization of HCl by NaOH. A solution of NaCl in water has no acidic or basic properties, since neither ion is capable of hydrolyzing.
