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)

Explanation / Answer

bleach NaClO , acetic acid = HC2H3O2

a)

NaCl(aq) + HC2H3O2(aq) <--> NaC2H3O2(aq) + HClO(aq)

net ionic:

ClO-(aq) + H+(aq) <--> HClO(aq)

b)

2NaCl(aq) + H2C6H6O6(aq) <--> Na2C6H6O6(aq) + 2HClO(aq)

net ionic:

2ClO-(aq) + 2H+(aq) <--> 2HClO(aq)

H2C6H6O6
