Web– rubidium hydroxide RbOH – cesium hydroxide CsOH A solution of a strong acid at concentration 1 M (1 mol/L) has a pH of 0. A solution of a strong alkali at concentration 1 M (1 mol/L) has a pH of 14. Thus, in most problems that arise pH values lie mostly in the range 0 to 14, though negative pH values and values above 14 are entirely possible. WebpH = -log [H+] pH = -log [0.00896] pH = 2.047 percentage h2so4 solution at ph 2 Because you know the pH value, you can calculate the H + ion concentration. When you know the H + ion concentration, H 2 SO 4 concentration can be found. Then, you can find amount and mass of H 2 SO 4 in a certain value.
