Ph of a solution defined
WebJun 14, 2024 · If pH > 7, then the solution is basic. This is known as the p H scale. The pH scale is the range of value s from 0 to 14 that describes the acidity or basicity of a solution. You can use p H to make a quick determination whether a given aqueous solution is acidic, basic, or neutral. WebThe pH of a solution is defined as the negative logarithm to the base 10, of the concentration of H + ions in solution in mol dm –3. pH is expressed mathematically as pH …
