Question

During lab you measured the pH of mixtures containing strong acid and strong base. Write net Brønsted equations that show the acid-base reactions of common household items. For polyprotic species (such as vitamin C, lemon juice, and washing soda), please show only one proton transfer. Remember that spectator ions are not included. (Use the lowest possible coefficients. Omit states-of-matter in your answer.)

(a)    bleach and vinegar (sodium hypochlorite and HC₂H₃O₂)

(b)    bleach and Vitamin C (sodium hypochlorite and H₂C₆H₆O₆)

Answer 1

(a)    Bleach and vinegar (sodium hypochlorite and HC₂H₃O₂)

ClO^- + CH₃COOH    $\rightarrow$ HClO + CH₃COO^-

(b)    Bleach and Vitamin C (sodium hypochlorite and H₂C₆H₆O₆)

ClO^- + H₂C₆H₆O₆   $\rightarrow$ HClO + HC₆H₆O₆^-
