To test if adding salt to water increases the boiling point of the water, do the following: boil a sample of pure water until it boils. Measure the temperature at which the pure water boils. Take another sample of pure water and add salt to it, then boil this sample under the same conditions. Measure the temperature at which the salt water boils. If the latter temperature is higher, salt does increase the boiling point of water.

What gas station has gasoline without ethanol in atlanta ga?
At this time all gas stations sell gas with ethanol in Pennsylvania, Maryland, Delaware, New York.

However some gas station are charging .10, .15 and even .25 cents more for gas that they say does not contain ethanol -----BUT IT DOES. THE NON ETHANOL THAT WAS IN THEIR TANKS RAN OUT WEEKS AGO AND THEY UP THE PRICE AND SAID THEY DO NOT HAVE IT.

How do you test for lipids using emulsion test?
The procedure is for the sample to be suspended in ethanol, allowing lipids present to dissolve. The ethanolic solution is then decanted into water. Since lipids do not dissolve in water, when the ethanol is diluted, it falls out of solution to give an emulsion. b8d7e385-e2f2-47f5-8c06-26f0aee337b6 Y2:b8d7e385-e2f2-47f5-8c06-26f0aee337b6
