The most common problem in the total alkalinity test is caused by a high level of chlorine. When excessive chlorine is present in the sample, one of the two reagents used in the total alkalinity indicator will bleach out. When this happens, the endpoint changes from blue to yellow instead of green to red. To avoid this problem, repeat the test with an extra drop of the first reagent, thiosulfate. This should destroy the excess chlorine and solve the problem. | The most common problem in the total alkalinity test is caused by a high level of chlorine.
