For the equation below at equilibrium, what is the shift in the equilibrium position upon adding sodium acetate to the equilibrium mixture of acetic acid and methyl orange, where HMO represents the protonated (acid) form of the indicator and MO- represents the deprotonated (or base) form of the indicator. What is the resulting color of the solution? HMO(aq) + H,O(1) H,O-(aq) + MO(aq) O to the left/red O to the right/yellow O to the left/yellow to the right/red
