Tips on how to support us to carry on to teach the leaders of currently and tomorrow about consuming h2o high quality troubles to realize our intention of Safe and sound drinking water staying available to each individual Canadian:

pOH（氢氧根离子浓度指数）是和pH相对应、表示溶液中氢氧根离子活度的概念，

pH is represented in the shape of the equation because the damaging logarithm on the Hydrogen ion concentration.

pH is a vital drinking water measurement, which can be generally measured the two within the sampling web-site and during the lab. There are actually huge and little designs of pH meters.
