This quick demonstration is a highly visual illustration of the use of acid-base indicators to determine pH. Milk of magnesia is mostly a suspension of magnesium hydroxide in water. Magnesium hydroxide is a strong base that readily neutralizes hydrochloric acid. Universal indicator is a mixture of several acid-base indicators. The changing colours of the indicator during this reaction help students to observe the pH changes that occur during neutralization.
