What is the pH and what does the pH of water means?

PH is chemical test for water that does mean that the chemical reaction of water is either Acidic PH water or Basic PH water or Neutral PH water that also means there is acidic water and basic water and natural water, don't be confused; I will explain what does the acidity or basicity of water mean?

Basically the Natural water must be Neutral i.e. the PH of neutral water must fall in 7.2 to 7.4 where the water dose not has any color or special smell or specific taste, where the WHO recommended that Tap water PH should fall between (6.5-8.5).

Again we talk about Acidic water is that water of PH level from 1-7.1 and acidity increases as we go down to (PH level of 1), this acidity of water make the taste of water unpalatable.

The Basic water sometimes called alkaline water is that water of PH level (above 7.4 to 14), such alkaline water pH found in Saltwater and the taste of Basic water unpalatable too.

The pH drops at night and rises during the daytime.

According to Dissolved chemicals and minerals change the balance of H+ and OH- ions of water which altered the pH value of water.

Affect the solubility of trace elements, the ability of water to form scale (if alkaline pH or saltwater) or cause corrosion of metal (acidic water), and the ability of water to support the living organisms

What is the difference between ionised, distilled, purified water?
Distilled water and deionized (DI) water have been the most common forms of purified water, Distilled water is produced by a process of distillation and has an electrical conductivity of not more than 11 µS/cm and total dissolved solids of less than 10 mg/litre, thus it is including vaporization or boiling then condeensing water.

PH of Distilled water not exactly neutral because vaporisation will not remove many volatile oils which make a little change in water hydrogen logarithm (PH).

Deionized water, also known as demineralized water / DM water, (DI water, DIW or de-ionized water), is water that has had its mineral ions removed, such as cations like sodium, calcium, iron, and copper, and anions such as chloride and sulfate. Deionization is a chemical process that uses specially manufactured ion-exchange resins which exchange hydrogen ion and hydroxide ion for dissolved minerals, which then recombine to form water. Because the majority of water impurities are dissolved salts, deionization produces a high purity water that is generally similar to distilled water, and this process is quick and without scale buildup.

PH of deionized water is supposed to be neutral (ph=7.0)

Common methods to purify water are Reverse osmosis, carbon filtration, microfiltration, ultrafiltration, ultraviolet oxidation, or electrodialysis as well as distillation by boiling.
