Restoring Balance Lab
king of beasts Tran IB Chemistry SL II R5 Ms. Crane January 4, 2012 Restoring symmetricalness LAB Pre- lab Questions 1. The solvability of iodine increases because the baffle of chemical equilibrium has shifted towards the triiodide stead of the reaction. Addition of the reactants causes an increase in the product which is directly connect to the solubility of iodine in piss supply in this case. 2. Ammonium chloride depart be to a greater extent soluble in bouncy water as in an wake up-absorbing reaction, increasing the temperature (which is the same as adding heat one of the reactants) will cause the smear of equilibrium to shift towards the products to compensate for the interchange.More products are a result of increased solubility of Ammonium Chloride with water when temperature is increased. Post Lab Questions 1. CoCl42- ions are present in this termination as they are sullen swarthy and the color of the Cobalt Chloride solution was blue when we recorded the c olor and appearance of the solution. 2. Co(H2O)62+ ion was kick upstairs by the appendix of water as it is rap colored and when we added water to the carbon monoxide gas chloride solution, it became pink. This was because the amount of Co(H2O)62+ ions went up( more(prenominal) pink) to compensate or thus far out the change.Adding more products resulted in the spatial relation of the equilibrium to shift towards the reactant side of meat qualification it favor the Co(H2O)62+ ions. 3. (a) CoCl42- ion is favored by the addition of hydrochloric sharp and calcium chloride. (b) Cl- ion (c) When the stress (Chlorine from hydrochloric acid and calcium chloride) is added on the reactant side (more reactants), the pink color reduces and blue color increases. In other words, CoCl42- is favored to compensate for the change or minimize the stress. 4. A. Adding a species which appears on the right side of an equation will shift the equilibrium to the left side of the equation.B. Adding a species which appears on the left side of an equation will shift the equilibrium to the right side of the equation. 5. Since acetone attracts water molecules (decrease water molecules from the reaction) the reaction tries to create more water. Making more of the product, it naturally makes more of all the products which creates CoCl42- ions (blue in color), resulting in a blue color of the system of chemicals. 6. (a) Ag+ + Cl- > AgCl (b) The concentration of Cl- ions decreased as chlorine ions from the reactant side reacted with silver
