Webb30 apr. 2014 · Let's assume the solution is 0.1M. NaOH is a strong base, so this will produce 0.1mol/L of OH ions in solution. This will produce a pH of 13. You will need to take the negative log of 0.1 to find the pOH. This will work out to be 1. Since pH + pOH = 14 We can calculate the pH to be 13.

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).
