Explanation:
Phenolphthalein is a pH indicator that is commonly used in chemistry experiments. It changes color depending on the pH of the solution it is added to.
In acidic solutions, phenolphthalein is colorless. As the pH of the solution increases and becomes more basic, phenolphthalein starts to turn pink.
Therefore, when substance X is added to phenolphthalein, it will cause the phenolphthalein to turn pink.
Summary:
- Phenolphthalein is a pH indicator
- In acidic solutions, phenolphthalein is colorless
- In basic solutions, phenolphthalein turns pink
- Substance X will cause phenolphthalein to turn pink
