Acids and bases are classes of materials that have different properties. Acid-base indicators change color depending on whether they are in acids or bases. Blueberries contain a substance called ...

Some substances are neutral, meaning they are neither an acid nor a base, like water. Acid-base indicators can tell us whether something is an acid, a base, or neutral. Indicators change color ...

IntroductionAn acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with ...

The other two posts have to do with making your own natural acid/base indicators. The first is called Anthocyanin, and can be extracted from Red Cabbage. Quite specific directions can be found here.

An indicator changes color when it encounters an acid or base. There are many different types of indicators, some that are liquids and others that are concentrated on little strips of "litmus" paper.

A Surprising as that must have been, there is a simple answer. Red wine is what chemists call an acid-base indicator. It was the wine, not the egg white, that changed color.
