pH stands for "percentage Hydrogen" and measures the acidity of a substance.
when water content is high it react with CO2 produced as a result of respiration and produce carbonic acid which lowers pH.
it references the pH level.
There is a product by HTH called PH Plus that will rise the PH content in your pool.
The kidneys maintain the pH and regulate water content in the blood. The kidneys also remove waste products and filter them into the bladder to be removed.
pH Scale:
Soil pH is largely a factor of the ratio of the soil's organic matter content to its mineral component. Soils high in organic matter have a lower pH. The kind of minerals can also have an effect on pH.
Tris pH 8.0 NaCl EDTA
Adjusting the chlorine content will almost certainly affect the pH, so it would be simpler to get the chlorine level correct first and then titrate to the proper pH.
In science or chemistry or anything similar, pH is defined as the acidity content or amount within something, and so soil pH refers to the amount of acid a sample or area of soil may contain.
Primarily it would be the mineral content. There are a number of additives that could be applied: PH Buffers, PH setters, PH Ups, PH Downs, substrates, some types of rocks, mineral additives, mineral depleters, waterchanges, etc.
pH of a strong acid would be '1' or '2' pH of a weak acid would be '5' or '6' . NB 'pH' is a logarithmic scale of the hydrogen ion content of a substance. The small/bigger the number, the greater/lesser the hydrogen ion content.
