1. By making qualitative observations about the sodium hydroxide and phenolphthalein in solution and by comparing the given solution to other familiar solutions containing phenolphthalein.
What is Phenolphthalein?
Phenolphthalein is an organic chemical that is used as a cathartic in medicine. Its chemical formula is C₂₀H₁₄O₄.
It is employed as an indicator in acid-base titration. In alkaline solutions, it turns pink to crimson, whereas in acid solutions, it is colorless.
For the purposes of the experiment, it is dissolved in alcohol and is slightly soluble in water.
Nakisha uses the scientific inquiry process to determine whether mixing other solutions with phenolphthalein will also create a pink color will be;
