2. Aluminium sulphate (alum) is added to water with a pH of 7.2. Based on the reaction below, calculate the total amount of alkalinity in the water consumed after alum is dosed at 30 mg/L. Report the answer in terms of equivalent amounts of CA2CO3. Alum pK, = 3.3. Al2(SO4)3 · 14H2O+6H2O → 2Al(OH)3(3) + 6H† + 3SO + 14H2
