Carrie's teacher hands out test tubes filled with different chemicals and tells the students to identify their liquid as an acid, base, or neutral chemical. Carrie's test tube contains a clear chemical. She adds phenolpthalein to her test tube and gently moves the tube from side to side. A few moments later, the chemical in the test tube turns bright pink. What type of chemical does Carrie have?

Answer:

Alkaline/basic chemical

Step-by-step explanation:

Generally, an acid/base indicator is a substance that change colour based on the degree of acidity or basicity of solutions.

Phenolphtalein is an acid/base indicator that is usually colorless in acidic solutions and turns bright pink once the solutions become basic or alkaline.
