Question

Student performs experiments on acids and bases. Which is not a scientific experiment?

She uses an acid-base indicator to measure the pH of four different solutions.

She mixes two solutions and measures their pH before and after.

She asks her lab partner which base he thinks is hardest to study. <-- my answer

She measures the temperature of a solution before and after adding H2SO4.

Answer 1

she ask her lab partner which base he thinks is hardest to study
you are correct because that not an experiment its a question

Answer 2

Answer: Option (c) is the correct answer.

Step-by-step explanation:

An experiment conducted by following a detailed and organized series of steps in such a manner that its result will reject or validate the hypothesis.

For example, using an acid-base indicator will help to measure the pH of a solution.

A scientific reaction is performed in controlled conditions with proper precautions unless it could be dangerous to perform the experiment.

Therefore, we can conclude that she asks her lab partner which base he thinks is hardest to study is not a scientific experiment.
