WebThe pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H ^+ + ion concentration. The pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although ... WebApr 8, 2024 · Place a small portion of pH paper (about 2 cm) on a white glazed tile.
