Water Quality Testing and Analysis

The video tutorial demonstrates various tests on Hill Country purified water, including chlorine, hardness, pH, and metals tests. The chlorine test shows no presence, while the hardness test reveals two grains of hardness, indicating a water softener was used. The pH test results in a level of 7.7, and the metals test shows significant iron content. The video concludes with a recommendation against using the water due to excessive iron.

What factor might affect the chlorine test results for the Hill Country purified water?

• The bottle is made of plastic, which interferes with the test.

• The water is too hot, causing inaccurate readings.

• The bottle is not full, leading to possible chlorine evaporation.

• The water is too cold, affecting the test.
