Mass and Chemical Reactions Lab Essay

Relationships in a Chemical Reaction Lab Introduction This lab focused on mass relationships at bottom a chemical reaction. To understand this lab first, it is necessary to understand the reaction that is going on in the reaction. The Copper (II) chloride hydrate reacts with atomic number 13 to produce Aluminum chloride, copper, and water. Theoretical yield and various other forms of yield must be understood too, theoretical yield is what amount of the product you should get theoretically gibe to your calculations experimental yield is the product you get after you finish the experiment.Because of error usually your experimental yield will be off from your theoretical yield. pct yield is the efficiency of the reaction to get to the theoretical yield. Data Collection And Processing Raw Data Table 1 Substance / Object and weed Table Substance / Object Mass ( 0. 01 g) 200mL beaker 67. 38 0. 01 g 200mL beaker + Copper 69. 39 0. 01 g Copper 2. 01 0. 01 g 200mL beaker + modify Cop per 68. 01 0. 01 g Dried Copper 0. 63 0. 01 g Qualitative DataBefore the reaction, the Copper (II) Chloride hydrate is a blue crystallized substance, the Aluminum was shiny and made wavy sounds, it has a smooth metallic feel to it. During the reaction initially when stir ruby the water the water turns blue. When the aluminum is placed into the hydrous CuCl? the water becomes a darker squashy substance. Steam is coming out of the water and aluminum is visibly dissolving. The aluminum is also turning black and vapor is forming along the sides. Foam like red pieces are forming and dropping. As the solid turns completely red the liquid is becoming clear again and is colorless.
