WebThe pH scale (as shown in the figure above) is used to measure the acidity or alkalinity of an aqueous solution. The pH scale is numbered between 0 to 14. For reference, the equation … WebThe concentration of hydrogen ions can vary across many orders of magnitude—from 1 to 0.00000000000001 moles per liter—and we express acidity on a logarithmic scale called the pH scale. 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).

WebTechnically, the pH scale measures the logarithmic concentration of hydrogen (H+) and hydroxide (OH-) ions, which make up water (H+ + OH- = H20). When both types of ions are in equal concentration, the pH is 7.0 or neutral. Below 7.0, the water is acidic (there are more hydrogen ions than hydroxide ions). WebpH Scale Principle: H+ ion concentration and pH relate inversely. OH- ion concentration and pH relate directly. The following statements may be made about the pH scale numbers. Complete some of them. a. Increasing pH means the H + ions are decreasing. b. Decreasing pH means H + ions are increasing. c. Increasing pH means OH - ions are d. clothing in japan
