WebbWithin the pH range of 1.3-4.3, the phosphate mainly creates a chemical complex with aluminium. At higher pH values (4.3-7.2), the phosphate ions are commonly in the form of hydrolysed phosphate ions. When the solution reaches pH values of 7.2 and higher, the phosphate ions form complexes with calcium and magnesium (Rayment and Lyons 2011). WebbCalculate the pH of a 0.1 M K2CO3 K 2 C O 3 solution.
