WebDec 1, 2016 · So $\mathrm{pH} = -\log(1\times 10^{-6.5}) = 6.5 = \mathrm{pOH}$ which gives $\mathrm{pH} + \mathrm{pOH} = 6.5+6.5 = 13$, not $14$ So is my math or chemistry wrong, or are there limitations on $\mathrm{pH} + \mathrm{pOH} = 14$? WebThe 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.
