WebThe pH scale is used to rank solutions in terms of acidity or basicity (alkalinity). Since the scale is based on pH values, it is logarithmic, meaning that a change of 1 pH unit corresponds to a ten-fold change in H ^+ + ion concentration. The pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although ... WebApr 12, 2024 · Question. what is the third step.

WebFor a strong acid or base you could say that it fully dissociates in water, and thus [HO-] = 0.025 mol/L. Thus pOH = -log10 (0.025) Now if you're not allowed a calculator you can do it approximately, first 0.025 is clearly 1/40 thus pOH = log10 (40) = 1+log10 (4) = 1 + 2 log10 (2), and log10 (2) is between 0 and 1, so you can roughly say it's 0 ... WebJan 30, 2024 · Salts of Weak Acids and Weak Bases. If Ka (cation) > Kb (anion) the solution of the salt is acidic. If Ka (cation) = Kb (anion) the solution of the salt is neutral. If Ka (cation) < Kb (anion) the solution of the salt is basic. side effects of acetylcholine inhibitors

WebTriprotic Acids. Our techniques for working diprotic acid or diprotic base equilibrium problems can be applied to triprotic acids and bases as well. To illustrate this, let's calculate the H 3 O + , H 3 PO 4, H 2 PO 4-, HPO 42- , and PO 43- concentrations at equilibrium in a 0.10 M H 3 PO 4 solution, for which Ka1 = 7.1 x 10 -3, Ka2 = 6.3 x 10 ...
