Which of the following statement is false ? [1994]a)Strontium decompos...
False Statement: Beryllium hydroxide is more basic than barium hydroxide.
Explanation:
1. Reactivity towards water:
- Strontium decomposes water more readily than beryllium. Strontium reacts vigorously with water to produce strontium hydroxide and hydrogen gas. On the other hand, beryllium reacts slowly with water and forms beryllium hydroxide and hydrogen gas.
2. Melting point of carbonates:
- Barium carbonate melts at a higher temperature than calcium carbonate. Barium carbonate has a higher melting point because of the smaller size of the Ba2+ ion, which leads to stronger electrostatic forces of attraction between the ions.
3. Solubility of hydroxides:
- Barium hydroxide is more soluble in water than magnesium hydroxide. Barium hydroxide is a strong base and is highly soluble in water, whereas magnesium hydroxide is a weak base and is sparingly soluble in water.
4. Basicity of hydroxides:
- Beryllium hydroxide is not more basic than barium hydroxide. Beryllium hydroxide is a weak base and is less basic than barium hydroxide, which is a strong base. This is because of the smaller size of the Be2+ ion, which leads to a higher charge density and a stronger attraction towards the hydroxide ion.
In conclusion, the false statement is option 'D', which states that Beryllium hydroxide is more basic than barium hydroxide, which is incorrect.

Obviously it's D bcoz down the gp metallic nature increases so basic nature in creases so barium hydroxide should be more basic thn beryllium hydroxide and statement D is opp to this
