The following graph was produced using the data collected in the second part of the lab. Answer the questions below based on the videos and graph provided. Strong Bases/Acids vs. Weak Bases/Acids The 4 Titration Curves · Combinations N2OH + HCI Strong Base + Strong Acid NaOH + CH,COOH Strong Base Weak Acid NH,OH + HCI Weak Base Strong Acid NH.OH • CH;COOH Weak Base Weak Acid a. Explain why two titrations started at a higher pH value and two titrations started at a lower pH value, yet each titration started with the same concentration for the acid. b. What was the purpose of adding the indicator to each titration? C. Two titrations ended with the pH well above 10 the other two titrations ended with the pH below 10. Explain why this occurred.
