Scientific Inquiry

Question 12 • FL-2003010-M/J Physical Science

In a laboratory, Nakisha mixes a sodium hydroxide solution with an indicator called phenolphthalein. When combined, they create a pink solution. Nakisha wonders if mixing other solutions with phenolphthalein will also create this pink color. How could Nakisha use the scientific inquiry process to determine whether mixing other solutions with phenolphthalein will also create a pink color? Check all that apply.by making qualitative observations about the sodium hydroxide and phenolphthalein in solutionby asking a classmate if sodium hydroxide turns pink when mixed with other solutionsby comparing the given solution to other familiar solutions containing phenolphthaleinby designing an experiment to test phenolphthalein with other solutionsby repeating the experiment at different temperatures
