A group of students wrote the following procedure for their acid rain investigation.

Procedure:

1. Find the mass of each of three different building materials being tested.

2. Pour 200 mL of acidified water, pH 4.5, into each of three clean containers.

3. Place each sample of building material into one of the three containers.

4. After two days, remove the samples, wash them with distilled water, and allow them to dry completely.

5. Mass each sample.

The 200 mL of acidified water is a(n)
