WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. WebNov 30, 2024 · In chemistry, pH is a scale used to measure the relative acidity or basicity of an aqueous solution—that is, one in which a solute (salt, sugar, etc.) is dissolved in water. Because only aqueous solutions have pH levels, vegetable oil has no pH value. Likewise, other oils such as animal and petrochemical oils also have no pH value.
