The following plot shows the pH curves for the titrations of various acids with 0.10 M NaOH
Question:
a. Which pH curve corresponds to the weakest acid?
b. Which pH curve corresponds to the strongest acid? Which point on the pH curve would you examine to see if this acid is a strong acid or a weak acid (assuming you did not know the initial concentration of the acid)?
c. Which pH curve corresponds to an acid with Ka. 1 Ã 106?
12.0 100 8.0 6.0 40 2.0 0 10 20 30 40 50 6 Vol0.10 M NaOH added im

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.
