WebEven though pH is a unitless value but it is not a random scale. The value is due to the activity of H+ ion in the solution. pH is described as “the negative of the logarithm of the molar hydronium-ion concentration.”. pH Formula is expressed as. p H = − l o g [ H 3 0 +] The pH Formula can also be expressed as. p H = − l o g [ H +]
WebSep 30, 2024 · The pH scale shows how acidic or basic a chemical is in aqueous solution (mixed with water). The scale funs from 0 (most acidic) to 14 (most alkaline or basic), where 7 is neutral pH. Chemicals with pH values from 0 up to 7 are acids, those with a pH value of 7 are neutral, and those with pH values greater than 7 up to 14 are bases. how to rotate your screen on macWebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14.
