In chemistry what is a buffer
WebSep 15, 2024 · A buffer (or buffered) solution is one that resists a change in its pH when H + or OH – ions are added or removed owing to some other reaction taking place in the same solution. Buffers do so by being composed of certain pairs of solutes: either a weak acid plus its conjugate base or a weak base plus its conjugate acid. WebApr 10, 2024 · Science Chemistry What is the relationship between the point of maximum buffer capacity and the speciation diagram? In other words, is there a pattern of chemical behavior between the weak acid and weak base present in the solution at the point (s) of maximum buffer capacity?

WebBuffers are broadly divided into two types – acidic and alkaline buffer solutions. Acidic buffers are solutions that have a pH below 7 and contain a weak acid and one of its salts. For example, a mixture of acetic acid and sodium acetate acts as a buffer solution with a pH of about 4.75. Alkaline buffers, on the other hand, have a pH above 7 ...
