Question

The more alkaline a solution, the ______ the pH.

Answer 1

The more alkaline a solution, the higher the pH.

Explanation:

The more alkaline a solution, the higher the pH, because the pH value directly reflects a lower concentration of hydrogen ions and a greater concentration of hydroxide ions. Since the pH scale is logarithmic, each single-digit increase represents a tenfold increase in alkalinity. Therefore, highly caustic or strong alkaline substances will always register values closer to the maximum limit of 14.
