How do you calculate the ph
WebMay 1, 2024 · In a final volume of 210 ml (0.210 L), you can calculate final concentrations: [Ac-] = 0.008/0.210 = 0.038 M [HAc] = 0.012/0.210 = 0.057 M You can then use the HH equation as you did, substituting these concentrations. Do similar calculation for addition of NaOH where HAc will decrease and Ac- will increase.

WebMar 13, 2024 · Working with such numbers is inconvenient, so to makes things easier, chemists have defined the pKa number as: pKa = -log Ka. According to this definition, the pKa value for hydrochloric acid is -log 10 7 = -7, while the pKa for ascorbic acid is -log (1.6 x 10 -12) = 11.80. As is evident, the smaller the pKa number, the stronger the acid.

WebA pH (little p) of 7 only means neutral water at 25°C, but for other temperatures this means a pH above or below 7. This is due to the changing value of water's self-ionization constant, Kw, with temperature. At 25°C we know it to be 1.0 x 10^ (-14), but at something like 50°C it's about 5.5 x 10^ (-14).
