Heat of Solution
The project I chose was the Heat of Solution. The reason I decided to do this experiment specifically,was because I consider the heat given off by solution to be important. Whether it is useful in a science lab or in the outside world, the more you know, the better. Some of the materials I will be using are listed below: two beakers, 2 Styrofoam cups, a thermometer, a graduated cylinder, water, 40 g of Lithium Chloride, and 30 g of Potassium Chloride. When using all these materials in my experiment I am hoping to discover and compare the temperature of water when different salts are dissolved.
Before I begin my project, I need to go to my instructions and check what safety precautions I need to take to avoid any injuries. After that I will place a Styrofoam cup inside a 400 mL beakers. Thirdly, I will add 50 mL of water and record its temperature before continuing with my next step. After a couple of minutes I am to add 40 g of lithium chloride and record its temperature, which is very important to finding the heat of my solution. After this I will repeat the previous step and replace the 40 g of lithium chloride with 30 g of potassium chloride.
The way I will take note of my experiment will be through a narrative essay. So throughout my essay I will explain the personal experience/relation I have had with this experiment. I think this way of going in to detail about my experiment will be most effective because the reader will feel more connected with what is being accomplished because they will have an example from my life that explains the importance of my experiment. Seeing as how I have everything I will be doing in order, I am confident that my PBL will be a success.
