An analytical chemist is titrating 221.6 ml of a 0.2800 M solution of dimethylamine ((CH3)2NH) with a 0.2700 M solution of HNO, The pK, of dimethylamine is 3.27. Calculate the pH of the base solution after the chemist has added 190.6 ml of the HINO, solution to it.

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.
