WebThe letters pH stand for the power of the hydrogen ion. The pH of a solution is the negative logarithm of the hydrogen-ion concentration. pH = -log [H + ] In pure water or a neutral solution the [H + ] = 1.0 × 10 -7 M. Substituting into the pH expression: pH = -log [1.0 × 10 -7 ] = - (-7.00) = 7.00 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.

WebJan 30, 2024 · The quantity pH, or "power of hydrogen," is a numerical representation of the acidity or basicity of a solution. It can be used to calculate the concentration of hydrogen … Webvalues increase or decrease by a power of 10. The pH scale is a negative logarithmic scale, so a decrease in pH of 1 unit is actually a ten-fold increase in the amount of hydrogen ions. A solution with a pH of 5.0 is 100 times more acidic than a neutral substance of pH 7.0 . What does pH mean for life? graph inverse linear function
