Unformatted text preview: Farshad Hosseini Chemistry 12 Block 1-1 Equilibrium Minilab 2CrO 4 2- (aq) + 2H + (aq) Cr 2 O 7 2- (aq) + H 2 O (l) 1. When you add NaOH to the above reaction, the NaOH breaks apart Na + and OH- . The OH- ion reacts with H + ion to form water. This reaction results in the initial concentration of H + ion to go down and decrease. Therefore, the whole reaction would shift towards the reactants and result in a yellow colour in the reaction. 2. When HCL is added to the reaction, it breaks apart to form H + and Cl- ions. This results in the concentration of H + ion in the reactants to increase. This increase causes the reaction to shift towards the products, and therefore change the initial yellow colour in the reaction to change to orange. 3. a) When you add NaOH to the reaction, it breaks apart to form Na + and OH- ions.
