Sodium hydroxide, naoh; sodium phosphate, na3po4; and sodium nitrate, nano3, are all common chemicals used in cleanser formulation. rank the compounds in order from largest mass percent of sodium to smallest mass percent of sodium.

NaOH:
 (1x23) / (1x23 + 1x16 + 1x1) = 57.5 %

Na3PO4 
 (3x23) / (3x23 + 1x31 + 4x16) = 42.07%

NaNO3
 (1x23) / (1x23 + 1x14 + 3x16) = 27.05%

So, NaOH > Na3PO4 > NaNO3 

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.
