Answer 2

Answer:

An indicator is a large organic molecule that works somewhat like a " color dye". Whereas most dyes do not change color with the amount of acid or base present, there are many molecules, known as acid - base indicators , which do respond to a change in the hydrogen ion concentration.

Acid: turns red

Color: Blue Litmus

Base: stays same
