The ph scales
Webb1 okt. 2024 · Because pH is measured on a log scale, the pH value of a solution is equal to the negative logarithm of the hydrogen ion concentration. We can use the equation pH = -log[H +] where [H +] represents the hydrogen ion concentration in solution.Taking the negative log of the H + concentration ensures we end up with a positive pH value. This … Webb9 mars 2024 · pH = −log [H +] pH is usually (but not always) between 0 and 14. Knowing the dependence of pH on [H + ], we can summarize as follows: If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is basic. This is known as the pH scale and is the range of values from 0 to 14 that describes the ...
