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.\n□ by making qualitative observations about the sodium hydroxide and phenolphthalein in solution\n□ by asking a classmate if sodium hydroxide turns pink when mixed with other solutions\n□ by comparing the given solution to other familiar solutions containing phenolphthalein\n□ by designing an experiment to test phenolphthalein with other solutions\n□ by repeating the experiment at different temperatures

Answer

Brief Explanations:

  • Making qualitative observations helps in understanding the initial reaction. Comparing with familiar solutions gives a reference. Designing an experiment directly tests the hypothesis. Repeating at different temperatures can check for temperature - related effects. Asking a classmate is not part of the scientific inquiry process as it is not an independent investigation.

Answer:

  • by making qualitative observations about the sodium hydroxide and phenolphthalein in solution
  • by comparing the given solution to other familiar solutions containing phenolphthalein
  • by designing an experiment to test phenolphthalein with other solutions
  • by repeating the experiment at different temperatures
