You are given the following acidbase titration data, where each point on the graph represents the pH
Question:
a. What substance is being titrated, a strong acid, strong base, weak acid, or weak base?
b. What is the pH at the equivalence point of the tiration?
c. What indicator might you use to perform this titration? Explain.
14 12 10 6 20 40 60 Volume of titrant (mL)

A substance that alters color in solution over a constrained range of pH values is known as a pH indicator or acid-base indicator. The indicator chemical just needs to alter color slightly in order to be noticed. Indicators work on the basis that they react with water to produce the hydrogen cation H+ or hydronium ion H3O+. The indicator molecule\\\'s color changes as a result of the reaction. Since indicators have distinct color ranges for color change, they can occasionally be combined to provide color changes over a wider pH range.
