WebEach symbol in the box below represents a mole of a component in one liter of a buffer solution; represents the anion (X-), = the weak acid (HX), = H+, and =OH. Water molecules and the few H+ and OH- ions from the dissociation of HX and X- are not shown. The box contains 10 mol of a weak acid, , in a liter of solution. Webup the same way as any other equilibrium expression. Many common weak acids are oxyacids, like phosphoric acid and nitrous acid. Other common weak acids are organic acids— those that contain a carboxyl group, the COOH group, like acetic acid and benzoic acid. For weak acid reactions: HA + H2O R H3O + + A− Ka = [H3O +][A−] < < 1 [HA]

WebIn the diagram above, we see a neutral atom of sodium, Na, losing an electron. The result is that the sodium ion, Na ^+ +, has 11 protons, but only 10 electrons. Thus, the sodium ion has a net charge of 1+, and it has become a cation —a positively charged ion. Next, we’ll look at the formation of an anion—an ion with a net negative charge. WebThe pH scale is used to rank solutions in terms of how acidic or how basic they are. It indicates the concentration of hydrogen ions (H+) and hydroxide ions (OH-) in a solution. These ion concentrations are equal in pure water, which has a pH of 7. This pH value of 7 is important because it indicates a neutral solution.
