Every unit represent the activity of the ion H+.
Each pH unit on the pH scale represents a tenfold change in the hydrogen ion concentration. For example, a pH of 4 has 10 times more hydrogen ions than a pH of 5, and 100 times more hydrogen ions than a pH of 6.
The pH scale measures the acidity or basicity of a solution on a scale of 0 to 14. A pH of 7 is considered neutral, with lower values indicating acidity and higher values indicating basicity. Each unit change in pH represents a tenfold change in the concentration of hydrogen ions in the solution. The pH scale is logarithmic, meaning a difference of one unit corresponds to a tenfold difference in hydrogen ion concentration.
Scientists
Each increment or step on the pH scale is 1 order of magnitude or 10 times the previous step.
No, pH 9 is actually more basic (alkaline) than pH 4. The pH scale is logarithmic, so each unit is 10 times more acidic or basic than the unit next to it. pH 4 is more acidic than pH 9.
ten-folded
The unit for pH in a solution is a dimensionless unit that measures the acidity or basicity of a solution on a scale from 0 to 14.
Bases are repestented by values greater than 7 on the pH scale.
The unit of measurement for pH is a logarithmic scale ranging from 0 to 14 that measures the acidity or alkalinity of a substance.
All numbers below 7. Acidity increases with decreasing number, for example, 1 is the most acidic.

No, the pH value is not unitless. It is a unit of measurement that indicates the acidity or alkalinity of a substance on a scale of 0 to 14.
pH meters are precise to +/- 0.1 to +/- 0.01 pH unit (+/- 6 to +/- 0.6 mV) qith a full-meter scale of 14 pH units (about 840 mV)
Each increment or step on the pH scale is 1 order of magnitude or 10 times the previous step.
