![A 100.0 mL solution containing 0.893 g of maleic acid (MW = 116.072 g/mol) is titrated with 0.327 M KOH. Calculate
the pH of the solution after the addition of 47.0 mL of the KOH solution. Maleic acid has pK, values of 1.92 and 6.27.
pH
12.88
Incorrect
At this pH, calculate the concentration of each form of maleic acid in the solution at equilibrium. The three forms of
maleic acid are abbreviated as H,M, HM¯, and M²-, which represent the fully protonated, intermediate, and fully
deprotonated forms, respectively.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff6fc9156-ad81-46da-9d58-69aa61feda66%2F7b3be42a-32ad-465c-a6ee-2012f28d228d%2Fzgj34e_processed.png&w=3840&q=75)
