Melting Ice with Salt

My experiment is which type of salt can melt ice the fastest. I used three types of salt, epsom, table, and sea. I think that epsom salt will melt the ice the fastest. I chose this topic because I thought it would be interesting to find out which type of salt would melt ice the fastest, and also learn something else about salt along the way.

I did my experiment by freezing water into ice, taking leveled a teaspoon of each salt, next putting the salt into the ice, and finally setting a timer for one hour. After one hour has passed, I took a spoon, placed it onto the ice, and tilted the ice so it slowly poured into another cup. Next I measured the amount of ice melted, and found the avg.I applied this step to all three things of salt and ice, using the same sized cup for each one.

When finished my experiment, I found that table salt melts ice the fastest. The avg for table salt was 50.4 ml, sea salt was 50.16 ml, and epsom salt 45.27 ml. When melting each type of salt everything stayed the same, the ice, the time limit, and the measuring tool used. Each type of salt is used for different reasons, so I didn’t expect the results to be so close. Overall sea salt melted the ice the fastest, and epsom salt the slowest.

In this experiment, I learned that table salt melts ice the fastest. My hypothesis was incorrect because I predicted that epsom salt would melt the fastest. I’m not 100% sure my experiment was accurate because each salt was placed in the cup about 2 seconds apart. The avg for table salt was 1.18 cm, sea salt was 1.14 cm, and epsom salt 0.87 cm. This experiment could have been improved by Using something else besides ice because you have to make sure the water is at the right height, and it takes about a day and a half for the ice to freeze completely.

For my procedure, first I poured an even amount of water into three cups. Next I froze the water for a day and a half
