pH stands for 'potential of hydrogen' which has to do with the amount of ionic hydrogen present. This determines the alkalinity or acidity of a substance. So basically, pH is how acid or alkaline something is. The pH scale runs from 1 to 14. 7 is neutral - pure water for example has a pH of seven, although drinking water supplies have things added that change the pH and may range from 6-8. Anything with a pH above seven is said to be alkaline, below seven is acidic. A pH of 5 would be seen in, for example, an acid pool or a peat bog. A pH of 3 is an average laboratory acid, and a pH of 1 is the most acid that something can get (although this is not a measure of how strong it is technically). At the other end of the scale, a pH of 9-9.5 would be seen in the mineral-rich African Rift Lakes, around 12 is bleach, and 14 is extremely alkaline.

∙ 10y agoA pH scale is a measurement system used to indicate the concentration of hydrogen ions in solution; ranges from 0 to 14. In other words, the pH scale shows the acidity or basicity of a substance. 7 is when the pH of something becomes neutral, for instance, water. The concentration of hydrogen ions determine the acidity or basicity, so water has a concentration of 1x 10 to the negative seventh power. A pH of 6 is a concentration of 10, and gets 10 times more concentrated as the pH gets decreased by 1. A pH of 8 has the concentration of 1/10, and gets 10 times less concentrated as the pH gets increased by one.

∙ 12y agoThe pH scale is a scale determining how alkali, neutral or acidic a substance. You use it like this. If something has a pH ranging from 0-6 it's considered acidic. If something has a pH of 7 it is acidic. If something has a pH of 8-14 it is basic or alkali.

∙ 16y agoIt's a scale to measure acidity ranging from 1( most acidic) to 14 (most alkalinic), 7 being water, a perfect neutral.

∙ 6y agoThe range of pH scale is 0-14; the numbers are related to the activity of hydrogen ions in the solution.
pH=7 is neutral, pH over 7 is basic, pH under 7 is acidic.

What scale is used to indicate whether something is acid or alkaline?
The pH scale is the widely used universal scale, (which measures the hydrogen ion concentration of solutions) to measure the acidity or alkalinity of chemical solutions. It should be mentioned that the pH value is dependent on the temperature.
