What are folds in pH?

The pH is the negative logarithm (base ten) of the hydrogen ion concentration in a solution. An increase of one pH unit implies a ten-fold increase in hydrogen ion concentration. At a neutral pH of 7 there are equal numbers of hydrogen ions and hydroxyl ions.

Is a pH of 8.3 acidic or basic?

Knowing the dependence of pH on [H +], we can summarize as follows: If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is basic.

When the concentration of hydrogen ions is changed by 10 fold How many pH units change is this?

one pH unit
Because the pH scale is logarithmic (pH = -log[H+]), a change of one pH unit corresponds to a ten-fold change in hydrogen ion concentration (Figure 1).
