(iii) All alkaline earth metals form oxo salts such as carbonates, sulphates and nitrates. Both ion and ion are smaller in size. Why are lithium salts commonly hydrated and those of the other alkali ions usually anhydrous? It is an important laboratory reagent both in qualitative and quantitative analysis, The chemical name is calcium oxide and the formula is. For example, PbSO4 is insoluble because rule 3 comes before rule 6. Ether will extract the cerium nitrate from 5N nitric acid. Hence lattice energy during formation is very high and it is not overcome by the hydration energy. Greater the size of hydrated ion less is mobility. So, therefore, it is insoluble in water. Question 10.29 How would you explain the following observations? 2H2O. When you look back in life , this app would have played a huge role in laying the foundation of your career decisions.
