Strength of an acid or base depends on the degree to which it ionizes (dissociates) in water in the following reactions, an acid or a base reacts with water to produce conjugates strong acid is an effective proton donor that is assumed to completely dissociate in water. Acids and bases hl revision the following is a plain text extract of the pdf sample above, taken from our ib chemistry sl and hl outlines this text version has had its formatting removed so pay attention to its contents alone rather than its presentation. Lewis acids and bases are defined according to whether a chemical is an electron pair acceptor (acid) or electron pair donor (base) other definitions involve protons and hydroxide ions other definitions involve protons and hydroxide ions.

Chapter 8, acid-base equilibria road map of acid-base equilibria on first encounter, the study of acid-base equilibria is a little like a strange land with seemingly so that bases have ph greater than 7, at 25°c calculate the ph and poh of the following hcl solutions, assuming the hcl dissociates.

First, it helps to understand what acids and bases are acids are chemicals with a ph less than 7 that can donate a proton or h + ion in a reaction bases have a ph greater than 7 and can accept a proton or produce an oh-ion in a reaction if you mix equal amounts of a strong acid and a strong base, the two chemicals essentially cancel each other out and produce a salt and water.

Acids and bases what is an acid or a base by the 1884 definition of svante arrhenius (sweden), an acid is a material that can release a proton or hydrogen ion (h +) hydrogen chloride in water solution ionizes and becomes hydrogen ions and chloride ions. Theories of acids and bases this page describes the arrhenius, bronsted-lowry, and lewis theories of acids and bases, and explains the relationships between them it also explains the concept of a conjugate pair - an acid and its conjugate base, or a base and its conjugate acid.

Acid base base acid b acid base acid base c1 mol dm–3 solutions of the acids below are taken nitric acid b (i) define a lewis acid and state an example that is not a brønsted-lowry acid. K a is a constant which describes the ionisation of an acid (ie how strong it is) and k b does the same for bases pka is the log form of ka, defined as pka = -log(ka) and pkb = -log(kb) like previously with the ph scale, a 1 fold change in pka will signify a ten fold change in ka and the same for kb.
