Transcript of Which Salt is The Best?

Ammonium Chloride
The improvements that we could have done was lowering the amount of water used. We used 60 ml of water for 1 gram of salt, which potentially hindered the decrease of temperature.
: To determine which salt is best to use in a fast-acting cold pack.

: In an icepack there are two separate compartments. One contains salt and the other contains water. When the icepack is broken, the salt and water combine together. The salt lowers the temperature of the water to maintain the coldness.

: We predicted that Ammonium Chloride was going to be the best salt to make an effective cold pack.
Which Salt is The Best?
By: Naomi, Candy, and Juliet
Ammonium Chloride is the best because when temperature lowers, molarity lowers as well. Ammonium Chloride has a molarity of 0.312 M, whereas Potassium Chloride has a molarity of 2.2 M, making Ammonium Chloride the most effective salt to decrease the temperature of water.
