What is the boiling point of salty water?
So yes, salt increases the boiling temperature, but not by very much. If you add 20 grams of salt to five litres of water, instead of boiling at 100° C, it’ll boil at 100.04° C. So a big spoon of salt in a pot of water will increase the boiling point by four hundredths of a degree!

What lowers the boiling point of water?
Sugar, salt or other non-volatile solutes in water will usually make the boiling point higher. Alcohol, in contrast, is a volatile chemical that lowers the boiling point of water. Even a large amount dissolved in the water will usually make only small changes in the boiling point.
Do you add salt before or after boiling water?
Ideally, you should wait until your water is at a rolling boil. The boiling water will agitate and dissolve the salt quickly. You can add salt to your cold water if your prefer, though.
What makes water boil?

Is it OK to drink salt water everyday?
Drinking salt water potentially causes kidney damage
