Question
Consider the equilibrium H_2O(l) + HC_2H_3O_2(aq) H_3O^+ (aq) + C_2H_3O_2^-(aq) Why will the addition of NaOH to a solution of acetic acid cause the concentration of the acetate ion (C_2H_3O_2^-) to increase? Write chemical equations for the equilibria that you will observe during this experiment. a. Fe^+3 and SCN with Fe(SCN)^+2 b. Ni^+2 and NH_3 with Ni(NH_3)^+2_6 c. Color change of methyl orange vs.pH d. Solubility of Ca(OH_)2 e. Co^+2 and Cr^- with CoCl^-2_4 What special safety rules must be observed during this experiment?Explanation / Answer
Ans 3 : Addition of NaOH in acetic acid cause the reaction to go in forwarded direction. Acid base combine to give salt and water and it is fast reaction. So concentration of acetate ion increases.
