(a) The following analysis was obtained on a water sample. (i) Determine whether the analysis above is accurate within acceptable limits (8) (ii) If the analysis is not acceptable, identify and calculate the concentration of the missing species (5) (iii)Draw a bar diagram of the water sample in the table above and calculate the values of all the different hardness species i.e. carbonate and non-carbonate hardness expressed as mg/LCaCO3 (b) A phosphate producer spilled water in a water source in Mpumalanga Province. It has been claimed that the effluent is not in the form of phosphoric acid but rather it is disodium phosphate (Na2HPO4). The estimated total phosphate concentration in the water source is 102M and it is estimated that the total carbonate concentration in the river is 103M. Determine the proton condition for this system, assuming that the total carbonate is added to the system as carbonate (CO32)
