THE BUFFER IN LEMONADE : Determine which solution, buffered or unbuffered reacted with more moles of NaOH when the equivalence point was reached?

THE BUFFER IN LEMONADE

•Titrate the lemonade drink and the 0.010 M citric acid with a base solution of sodium hydroxide, NaOH and compare the pH changes in the buffered lemonade drink and unbuffered solution of citric acid.

•Use pH sensor and monitor changes in the pH of a buffer; observe the effects
of buffering on the pH titration curve

1.Determine which solution, buffered or unbuffered reacted with more moles of NaOH when the
equivalence point was reached?
2. Observe the graph of each titration. How does the titration curve of the buffered lemonade
compare to the curve of the unbuffered citric acid solution?
3. What is the formula of citric acid and the sodium salt of citric acid?
