1.	Equimolar solutions of the following were prepared in water separately. Which one of the solutions will record the highest pH ?
Answer» `SrCl_2` `BaCl_2` `MgCl_2` `CaCl_2` Solution :The highest pH will be recorded by the most basic solution. The basic NATURE of hydroxides of alkaline earth METALS INCREASE as we move from Mg to BA and THUS the solution of `BaCl_2` in water will be most basic and so it will have highest pH.
