2. Explain the effect upon the equilibrium, if any, for each of the substances added (sodium acetate, sodium hydroxide and hydrochloric acid). If you believe that the addition effects the position of the equilibrium, indicate whether the equilibrium shifts toward reactants or products and why. Adding sodium acetate: Adding sodium hydroxide: Adding hydrochloric acid: Data: Observation Test solution Initial Acetic acid + methyl orange А Acetic Acid + methyl orange + first NaC,H,O2 Acetic Acid + methyl orange + second...

Le
Chateler's principle
In the chart below: • Indicate the color of each solution as darker or lighter than the control after the addition of the specified substance. • Indicate the direction the equilibrium shifted as "toward products" or "toward reactants" based on the color change. • Based on the direction of the shift, indicate the substance(s) that increased which will either be the two reactants present on the reactant side of the equilibrium equation or the complex present on...

(b) Saturated Barium Chromate. Watch Video-3b where to 3 mL of 0.1 M BaCl2, 5-6 drops of 1 MK2CrO4 are added, and then 10 to 12 drops of 6 M HCI. Write down the chemical reaction(s) involved (you might look back at Part la), being sure to include the state of matter of all reactants and products so it is clear if there is a solid/precipitate expected.

1. Methyl orange, HMO, is a common acid-base indicator. In solution it ionizes according to the equation: HMO(aq) = H(aq) + MO"(aq) red yellow If methyl orange is added to distilled water, the solution turns yellow. If a drop or two of 6 M HCl is added to the yellow solution, it turns red. If to that solution one adds a few drops of 6 M NaOH the color reverts to yellow a. Why does adding 6 M HCl to...
