RE: pH Titration for Justin Mathison

Mr. Earl, The results of experiments on acidification of domestic water sampled at 1340 Brozio Rd.

are described below. The original intent was to investigate the efficacy of sulfuric acid, acetic acid, and carbon dioxide for neutralizing water provided from the residence. Results of early titration experiments indicated that strong acid neutralization was unnecessary, so sulfuric acid was dropped from the test plan.

Titrations were started with commercially available 36% acetic acid. For reference, white vinegar’s acetic acid content ranges from 5-20%. Less than 0.1 mL of 36% acetic acid reduced the pH of 100 mL of water to 4.2. The experiment was then repeated with 3.6% acetic acid to determine if commonly available white vinegar would be appropriate for neutralization. This second experiment showed that 0.15 mL, the equivalent of 3 drops, of 3.6% acetic acid could reduce the pH of 100 mL of water from 10.2 to 6.1. This indicates that one gallon of 5% acetic acid vinegar would be able to neutralize approximately 1000 gallons of water. At this rate, it would take around 12 gallons of vinegar a month to neutralize the water used by a family of four.

Because the water in question was relatively poorly buffered simple aeration was substituted for the carbon dioxide titration. A typical aeration wand driven by an aquarium pump was placed in 100 mL of sample water, and pH measurements were taken periodically. A stable pH of 7.6 was reached after 90 minutes.

I recommend pursuing aeration as a means for neutralizing the water for two reasons.

The first is the obvious advantage of using a process with no consumable resources. The second is that during acidification tests, the neutralized sample developed a strong sulfur odor that was not present in either high pH samples or samples neutralized by aeration. Please contact me if you have any questions about the protocols used or the conclusion.

Best regards, Tom Williams Laboratory Manager http://www.urc.cc/ mailto:lab@urcmail.net
