The pH value of any solution is a number which simply represents the acidity and basicity of that solution. The pH value of any solution is numerically equal to the logarithm of the inverse of the ...

Acid/base indicators are described and used to identify substances as acids or bases. Indicators and the pH Scale: Acid/base indicators are described and used to identify substances as acids or bases.

However, water comes from different sources, like tap water or river water. These water samples have other substances dissolved in them. They might show up as slightly acidic or slightly alkaline ...

Note that (aq) stands for aqueous and means that the substance is in solution. Acids are often produced from non-metal oxides. For example, sulfur oxides make sulfuric acid. A base is chemically ...
