which term is
used for representing relative strength of acids alkalis
Answers
Answer:
By the end of this section, you will be able to:
Assess the relative strengths of acids and bases according to their ionization constants
Rationalize trends in acid–base strength in relation to molecular structure
Carry out equilibrium calculations for weak acid–base systems
We can rank the strengths of acids by the extent to which they ionize in aqueous solution. The reaction of an acid with water is given by the general expression:
HA(aq)+H2O(l)⇌H3O+(aq)+A−(aq)
Water is the base that reacts with the acid HA, A− is the conjugate base of the acid HA, and the hydronium ion is the conjugate acid of water. A strong acid yields 100% (or very nearly so) of H3O+ and A− when the acid ionizes in water; Figure 1 lists several strong acids. A weak acid gives small amounts of H3O+ and A−.
