Question
Please help HCH_3CO_2(aq) CH_3CO_2(aq) + H^+(aq) What color is the acetic acid plus methyl orange solution and what does this tell you about where the indicator equilibrium is? What color is the acetic acid plus methyl orange after addition of sodium acetate solution and what does this tell you about where the indicator equilibrium is? What color is the acetic acid plus methyl orange plus sodium acetate solution after addition of ammonium hydroxide and what does this tell you about where the indicator equilibrium is?Explanation / Answer
1) The colour of the solution is orangish and the indicator equilibrium is slightly towards the right.
2) The clour of the solution is yellowish as due to the formation of acetate ion from sodium acetate the dissociation of acetic acid reduces and the pH increase. The indicator equilibrium is towards left.
3) The addition of ammonium hydroxide makes the solution basic and hence the solution turns yellow
