i m unable to solve ionic equilibrium problems

Ionic equilibrium is one of the important topic in physical chemistry.First clear all the concepts of chemical equilibrium as its an foundation.Focus on solved problems of each type as it would help you in understanding what type of different questions are actually asked in this topic.Also it help you in understanding that how the initial concentration and equilibrium conc. are taken.Expression of equilibrium constant should be well cleared.For gaseous reactants and products how this expression gets changed.Practise the solved ones and then move to unsolved questions.Take some good book for numerical problems.All the best you can surely be able to sove such problems.
