Will the amount of salt affect its boiling temp.of water?
Definitely yes. The presence of any solute in water has the effect of lowering its freezing point and raising its boiling point. More salt will cause this effect to be greater. Well you see the salt can disolve in the water then it affects the temperature. Salt will increase the boiling temperature of water. The boiling point elevation for water is 0.52°C·kg/mol. Each mole of salt multiplied by the number of ions produced by its dissolving will elevate the boiling point of 1 kg of water by 0.52°C. If the salt is sodium chloride, a mole will produce 2 moles of ions (1 mole of sodium+ and 1 mole of chloride- ions). If you dissolve 1 mole (58.43 g) of NaCl in 1 kg of pure water the resulting solution will boil at 101.04°C.
