Question

Suppose that the student working besides you on the laboratory bench spills one of the liquids she is using in this experiment. - What reagent could you use to determine whether the spilled liquid is 0.10M NaOH? Briefly explain what you would observe using this reagent if the liquid were 0.10M NaOH.

Answer 1

You could collect a certain amount of the sample, add an equal amount of 0.10M HCl, and use a pH electrode to determine the pH. The two should react to form NaCl and water, so theoretically the pH should be 7.

Not sure if this is the answer that they're looking for, but it's my best guess.

Answer 2

thank you
