Question

alkaline earth metal hydroxide are weaker alkaline as compared to alkali metal hydroxide .why​

Answer 1

Alkaline earth metal hydroxide are weaker alkaline as compared to alkali metal hydroxide because alkali metal hydroxides are more basic and more stable than the alkaline earth metal hydroxides because

1. Ionisation energy of alkaline earth metals are more

2. Smaller size of ions of alkaline earth metal

3. Greater lattice energy of alkaline earth metal hydroxides

These makes alkaline earth metal hydroxides as less stable.
