Listenwhich change in the h + ion concentration of an aqueous solution represents a decrease of one unit on the ph scale?

The pH scale is a logarithmic scale that runs from 1 to 14.

1 is the lower limit of the scale and 14 is the upper limit of the scale. On a pH scale, to represent a decrease of one unit, the concentration of the hydrogen ion or the hydroxyl ion must change.

A decrease in 1 unit or 1 pH represents a concentration of 10moldm⁻³.

Note: pH = - log₁₀[H⁺]
