Determine ph of a weak acid solution
WebThe pH of a 2.00 M solution of a strong acid would be equal to −log (2.00) = −0.30 . The higher pH of the 2.00 M nitrous acid is consistent with it being a weak acid and therefore not as acidic as a strong acid would be. The procedure for calculating the pH of a solution of a weak base is similar to that of the weak acid in the sample problem. WebRemember, our goal was to calculate the pH of the resulting solution. So to calculate the pH, we're gonna need the concentration of acetic acid and the concentration of acetate …
