The purpose of day one was to identify the unknown white compound. The chemicals used the 1st day of the lab contain 1mL of 0.1M AgNO3, 6M HNO3, 6M NaOH, 0.1M BaCl2 and 1 mL of 6M HCl these chemicals were specifically chosen for the ion tests after the unknown dissolved in water, as mentioned on lab archives. In our entire experiment we used distilled water because routine tap water can produce many problems when used in sensitive lab like this. Distilled water is used because it is important to eliminate ions and minerals from the water in order to achieve the desired and particular the results The equipment we used included; several 40 mL sized beakers to mix the solutions in. 10 mL graduated cylinders to get precise water measurements. We used matches and Bunsen burner for the flame test. Used a stirring rod to mix the solutions with, while making sure the to wash and dry when using it different solutions. The first step of the experiment was to determine the solubility of the unknown white compound. The simple understanding of whether the UWC is a soluble in aqueous solution is important…show more content…
Chemicals that were used 2nd day were; MgCl2 and MgSO4 to determine if they have the same capability to melt ice. The equipment used was; 50mL beaker, Stirring rod, distilled water, their functions were the same as the 1st day. The conductivity probe tells the number of ions formed and the charge of the ions formed. The first test we did was to examine the capability for MgCl2, MgSO4, and UWC to melt ice. We filled beakers with 50 mL of ice, placed 0.0778g of UWC, 0.077g of MgCl2, and 0.077g of MgSO4 in individual beakers of ice and then let each beaker sit for 2 minutes. Then measured the volume of ice melted in mL. Finally, we compared the volume of water of the three compounds if they have the same ability to melt
