Chapter 12: Acids, Bases, Salts, and Buffers C. Acid-Base Indicators Dyes that change color as the pH changes are referred to as indicators. They are often used to locate the point at which exact amounts of acid and base have been reacted in neutralization reactions. Procedure 1. Place 20-drop samples of 0.05 M hydrochloric acid into each of five clean 10-cm test tubes. 2. Prepare five similar samples of 0.05 M sodium hydroxide. 3. Test each indicator listed in Table 12.5 by adding 1 drop of indicator to one of the HCl samples and 1 drop to one of the NaOH samples pre- pared in Steps 1 and 2. Mix well and record the resulting solution color in Table 12.5. TEST TUBE CONTENTS IN SINK. Disposal Behavior of Salts Solution The neutralization of an acid by a base produces a salt. If the acid and base the o that reacted are both strong, the resulting anion and ontion of tl
