ALTERNATIVES
If effervescent tablets are unavailable, the lab could be completed by timing how long it takes for 1 tsp salt to dissolve in water of a given temperature. However, this is not ideal, because it will take a long time for the salt to dissolve if the solution is not stirred. On the other hand, if the solution is stirred, care must be taken to do it at the same rate for all the tests, as more vigorous stirring will increase the rate at which the salt dissolves.
