"NettetAboutTranscript. The pH scale is a convenient way to represent the acidity or basicity of a solution. We can calculate the pH of a solution by taking the negative logarithm of the hydronium ion concentration, or pH = -log [H₃O⁺]. At 25°C, a solution with pH < 7 is acidic, a solution with pH > 7 is basic, and a solution with pH = 7 is neutral. " - How ph scale works

NettetThe pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH less than 7 is acidic. A pH greater than 7 is basic. The pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6. NettetpH is a logarithmic scale. This means that for each one-digit change in pH, the acidity (H + concentration) changes by 10 times. For example, a solution with a pH of 4 has 10 times more H + than a solution with a pH of 5. A solution of pH 3 will have 100 times more H + (it is 100 times more acidic) than a solution of pH 5.
