It is a measure of the concentration of hydronium (H30+11OH) ionic bonds in a solution. The greater the concentration of hydronium ions, the lower the pH and the more acidic it is. Solutions with a pH of less than two are considered strong acids. Solutions with a pH of greater than 12 are considered strong bases.

∙ 11y agoThe pH scale gives substances a label of how acidic, alkaline or neutral it is. For example, if someone says a solution has a pH of 3.2 you would automatically know that the substance was acidic. If the number given was 13, it would be very alkaline. The normal pH range is 0-14 and thus by a nice simple number, a good indication of acidity/basicity is given.

∙ 14y agoThe pH scale is measure of the concentration of Hydrogen ions. It measures how acid or alkaline a solution is. Water has a pH of 7 and is neutral. A pH of less than 7 is acid and more than 7 is alkaline. Each change in the pH value of 1 (e.g from 7 to 8) indicates a ten fold change in hydrogen ion concentration. In math terms : pH= log10 (conc H+)

∙ 13y agoIt is a measure of Acidity. Acidity is basically the concentration of hydrogen ions (H+) in a solution, due to say addition of Nitric acid, which in solution dissociates into Hydrogen and Nitrate ions. If the concentration of hydrogen ions is 1x10{to the power -3} the pH is said to be +3. Twice that concentration, it will be approximately +3.3
The definition is "The logarithm of the hydrogen ion concentration, with the sign reversed". For pure water at room(?) temperature, the pH is +7. Anything higher and it is "alkaline", lower is "acidic".

∙ 7y agoThe purpose of the pH scale is to evaluate the basicity or acidity of solutions; a pH under 7 is acidic, a pH over 7 is basic and pH 7 is neutral.

How would you describe the pH scale and its uses?
The pH is a measure of acidity/basicity of liquids. The pH scale is - by convention - between 0 an 14:- pH under 7: acid- pH=7: neutral- pH over 7: basic
What is the range of numbers used to describe how acidic or basic a solution is?
0- 14 the pH scale.
What scale is used to determine pH?
the pH scale
What number is highest on the pH scale?
The highest number on the pH scale is 14. The pH scale goes from 0 to 14.
What colour is acid on a PH scale?
The Ph scale does not have colours.
