Introduction This lab proposed the question of what happens when copper chloride and iron are combined and what is the balanced equation.By completing this lab‚ the goal was to determine the equation and product for the reaction of iron (Fe) and copper chloride (CuCl2). It was predicted either solid iron or solid copper would form. Methods To begin‚ 6.00026 grams of copper chloride was dissolved in 50ml of distilled water in order to have a solution with charged iron and chlorine atoms. Then‚ 6

The investigation was designed to determine the effect of the addition of increasing concentrations of a miscible liquid (ethanol) on the solubility of KNO3 in water. The results of the investigation support the hypothesis that water‚ which exhibits greater polarity‚ is able to dissolve a greater mass of KNO3 at lower temperatures compared to tested concentrations of Ethanol ranging from 12.5% to 30%. Furthermore‚ the results of the graph 1 show correspondence to the dielectric constant of each solvent
