Could you me to solve edta question?
1) in 10.00 ml calcium hydroxide we add 2 ml of ammonia buffer and five drops of calmagite indicator
if we add 50.00 ml of edta to reach endpoint how to calculate solubility?
2) why add calmagite indicator before edta titration?
3) they said blue color is endpoint so this mean in solution their only (ca+edta) complex?
