Why Does Salt Make Water Boil Faster Chemistry

It s because adding the salt lowered the heat capacity of the water.
One of the classic examples is to add salt to your water in order to get it to boil faster. These two changes actually work against each other. Adding salt to water doesn t make it boil faster it makes it hotter. Adding salt to water is going to do two things to water s physical properties.
This phenomenon occurs for all solute solvent systems regardless of. Maybe so much salt that some doesn t quite dissolve. This gives salt water a higher boiling. People might have noticed this sudden change in the water s temperature so they say that when you add salt in water it boils faster.
This means that it does not take as much energy to boost the temperature of salt water as it does to heat up pure water. It will raise the boiling point and it will lower the specific heat. The phenomenon depends on the number of particles formed in the solution. Adding salt to water increases the boiling point of water due to a fundamental colligative property of matter known as boiling point elevation.

Why does salt make water boil faster. Why does the salted water boil more quickly even though it has a higher boiling point. The heat capacity is the amount of energy needed to raise the temperature of water by 1 c. Adding salt to water actually boosts the boiling point a few degrees but even with the higher boiling point salt water boils faster than pure water because salt water has a lower heat capacity than pure water.
While i am not arguing that your results are wrong i would like to suggest you try the experiment again but this time put even more salt in the water. But is this actually true. If you add salt to water it will increase its boiling point from around 100 106.
