Part iii. acetic acid is a weak acid and establishes the following equilibrium in water: hc2h3o2(aq) + h2o(l) h3o+(aq) + c2h3o2-(aq). in part iii, the methyl orange indicator is used to monitor the equilibrium shifts of the acetic acid/acetate ion system. the methyl orange equilibrium established with water is hmo(aq)(orange-red) + h2o(l) h3o+(aq) + mo-(aq)(yellow). you compared the color of the solutions in three test tubes that initially contained 3 ml of 0.1 m acetic acid and a few drops of methyl orange indicator. in the first test tube, you added 1.0 m nac2h3o2 drop wise. what color change was observed and what did this color change indicate about the shift in the methyl orange equilibrium? a. the solution turned a more intense orange-red color indicating that the methyl orange equilibrium shifted to the left, producing more of the orange-red colored hmo. b. the solution turned yellow indicating that the methyl orange equilibrium shifted to the right, producing more of the yellow colored mo-. c. the solution turned yellow indicating that the methyl orange equilibrium shifted to the left, producing more of the yellow colored mo-. d. the solution turned a more intense orange-red color indicating that the methyl orange equilibrium shifted to the right, producing more of the orange-red colored hmo. e. no color change was observed indicating that equilibrium was unaffected.
