14/11/2013, · Stir the sample. (Note: Allowing ,wastewater, samples with a ,pH, greater than 7 to be exposed to carbon dioxide (CO 2 ) in the atmosphere can result in the formation of carbonic ,acid,, which will lower the sample’s ,pH value,—so minimize exposure to the air.) 3. Rinse electrode and ATC probe with DI water and blot dry.

From the above data and graphic representation of ,pH, content in the ,wastewater, of Phagwara shows that the ,pH, is alkaline in nature, but it decreasing from 2009 to 2011 & it also varies in different months due to the flush water and presence of aquatic bodies. The highest average ,pH, was observed in the month of July 8.71 and the lowest

The curve above is the actual titration results of the ,pH, Adjustment of an ,acid, (HCl) with a beginning ,pH, of 2.0 and an ending ,pH, of 11.0. Dilute Sodium Hydroxide (NaOH) was used as the neutralizing agent. A brief glance at the curve indicates that the process of ,pH neutralization, or ,pH, adjustment is not particularly easy.
