    I'm doing a lab for my IB Chemistry class where I'm determining the affect salt content has on the boiling point of tap water. As I was writing out the procedure, I said that I was going to time how long it takes for the water to boil. My question is, given the heat and the time it takes the water to boil, is there an equation to find the boiling point? If not, is there any other way to find it?

    "Books are the carriers of civilization. Without books, history is silent, literature dumb, science crippled, thought and speculation at a standstill. I think that there is nothing, not even crime, more opposed to poetry, to philosophy, ay, to life itself than this incessant business. " - Henry David Thoreau

    You would need to know the specific heat of your salt water solution and know the heat input accurately (eliminate or account for losses). If you have this information, then yes there is a simple equation you could use.

    In order to find the equation you will need to generate some experimental data then plot the results on graph paper, if the result is a straight line then the formula will be of the form y=mx+c. If the graph exhibits curvature then you will need to compare the result to functions such as y=Ae^kx
