No, it increases the boiling point. becomes lower. Let's look at why a salt water solution has a freezing point below zero, and how you can use this fact to make ice cream!
At the right is a container of water with an ice cube in it. The water and ice are at 0°C, which is the melting point of ice and the freezing point of water.
Molecules of ice are constantly escaping into the water (melting), and molecules of water are being captured on the surface of the ice (freezing).
When the rate of freezing is the same as the rate of melting, the amount of ice and the amount of water won't change. The ice and water are said to be in dynamic equilibrium with each other. The ice is melting, and the water is freezing, but both are occurring at the same rate, so there is no net change in either quantity.
This balance will be maintained as long as the water stays at 0°C, or unless something happens to favour one of the processes over the other.
Here is the same container, but where the water temperature is -10°C.
The molecules of water are moving more slowly, because they contain less heat. These slower-moving water molecules are more easily captured by the ice, and freezing occurs at a greater rate than melting.
Because there more water molecules being captured by the ice (being frozen) than there are ice molecules turni water, the net result is that the amount of water decreases, and more freezing is happening than melting, the water eventually all turns to ice.
This time we've warmed the water to 10°C.
Now the water of the ice, so not very many of them freeze. Freezing occurs at a slower rate than melting.
No
the water evaporates leaving salt crystal
Adding salt to water increases its boiling point, so it will take longer for the water to reach the boiling point and evaporate. Additionally, salt lowers the freezing point of water, making it harder for the water to freeze.
Salt water, but the water will stop boiling because upon adding the salt it raised the boiling point of water.
Adding salt to boiling water will actually make the water boil slower. Salt increases the boiling point of water by raising its boiling point temperature. As a result, it will take longer for the water to reach the new, higher boiling point temperature and thus boil.
No
the temperature of boiling water that is mixed with iodized salt will decrease.

No, salt does not evaporate in boiling water. When water boils, it turns into steam, leaving behind the salt in the water. Salt does not have a low enough boiling point to evaporate along with the water.
If you're talking about regular old table salt, then your answer is salt water--specifically boiling salt water.
Adding salt to boiling water will actually make the water boil slower. Salt increases the boiling point of water by raising its boiling point temperature. As a result, it will take longer for the water to reach the new, higher boiling point temperature and thus boil.
Adding salt to water actually increases its boiling point, so it will take longer for saltwater to boil compared to plain water. It is not recommended to add salt solely to make the water boil faster.
Adding salt to water raises the boiling point of the water. This occurs because salt ions disrupt the formation of water vapor bubbles, requiring a higher temperature for boiling to occur.
It is commonplace to put salt in water when boiling most foods. The reason why you put salt in with boiling water and vegetables is to help them retain moisture.
Adding more water will decrease the salt concentration.
