Lawrie Ryan and Roger Norris Solutions for Chapter: Further Aspects of Equilibria, Exercise 1: BEFORE YOU START

Write down the definition of a Bronsted-Lowry acid and Bronsted-Lowry base.
 

Explain the meaning of the terms: equilibrium, equilibrium constant, dissociation, strong acid, strong base, weak acid, weak base, neutralisation.

Make a list of strong acids and weak acids and strong bases and weak bases. 

Select a weak acid and write an equilibrium expression for the acid. Note that the process is the same as for writing equilibrium expressions for $\mathrm{K}$ that you used ${\mathrm{K}}_{\mathrm{a}}$ instead of ${\mathrm{K}}_{\mathrm{c}}$ .

Explain why the equation ${\mathrm{H}}^{+} + {\mathrm{OH}}^{-} \to {\mathrm{H}}_2\mathrm{O}$ applies to any acid-alkali reaction.

Write a paragraph describing how to carry out an experiment to find the enthalpy change of neutralisation of an acid by an alkali.

Explain the meaning of the terms: solute, solution, salt, sparingly soluble, polarisation, non-polar, enthalpy change, hydration.
