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?

10.063g / 10.00 ml = 1.0063 g/ml which rounds off to 4 sig figs as: 1.006 g/ml

You would be correct, boiling water does disinfect contamination.    the property of disinfecting means to kill  germs, bacteria and other pathogens or contamination  that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate.  the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
