If the two ions are of equal concentration, they form water, which is neutral. However, if H+ is greater than OH-, the substance is acidic, and otherwise, it’s basic. What Does pH Have to do With Water? The neutral pH of 7, located in the middle of the pH scale, is pure ...
Distilled water is a form of purified water. Distilled water is water that has been boiled into vapor and condensed back into liquid in a separate container. Impurities in the original water that do not boil below or near the boiling point of water remain in the original container. The pH ...

Hence the pH of normal rainwater is $5.6$ to $5.8$.Note:It must be noted that the pH value of pure water is $7$. This attribute is neutral, meaning it is neither acidic nor basic. The pH of normal, clean rain is between $5.0$ and $5.5$, which is mildly acidic. Rain ...
The presence of corrosive species (among them CO , H S and chlorides) has a pronounced effect on corrosion in producing wells. Carbon dioxide is almost always present and its effect on corrosion is primarily by decreasing the pH of the water phase. Carbon dioxide promotes general corrosion, ...

Although the pH of pure water is 7, drinking water and natural water exhibits a pH range because it contains dissolved minerals and gases. Surface waters typically range from pH 6.5 to 8.5, while groundwater ranges from pH 6 to 8.5. Water with a pH less than 6.5 is considered acidic. Th...
Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already become slightly more acidic over the last century. These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with ...
