Barium hydroxide is a team IIA metal hydroxide and it dissolves an extremely well in water to provide a solid base solution such as group IA steels hydroxides. Barium hydroxide dissociates completely in water to provide barium ions and also hydroxyl ions.

What is a strong base?
A strong base dissociate fully to the cation and also anion in the water. This reaction is a no a reversible one.
If OH- concentration is increased more and more, an easy strength of base increases.
Example: OH- concentration of aqueous ammonia solution is an extremely less as soon as it compare v OH- concentration the aqueous Ba(OH)2. As such aqueous ammonia systems is take into consideration as a weak base and also Ba(OH)2 together a strong base.
Solubility the Ba(OH)2
Solubility the Ba(OH)2 is better than Be(OH)2, Mg(OH)2, Ca(OH)2 and Sr(OH)2. The is the reason why barium hydroxide end up being a solid base than other group 2 metal hydroxides.
Dissociation of barium hydroxide in water
Now we know, Ba(OH)2 dissociate fully in the water.
How come prove barium hydroxide is a solid base practically? - determine pH
Prepare a 0.005 mol dm-3 barium hydroxide solution. You can prepare this equipment by measure up 0.86 g of Ba(OH)2 and dissolving the in 1 dm3 that distilled water. Then check the pH of all set barium hydroxide solution. You deserve to see the pH value is 12.
If pH worth is 12, OH- concentration must be 0.01 mol dm-3. The is as twice the ready Ba(OH)2 equipment concentration. Therefore it is clean that, barium hydroxide is a solid base and dissociate completely in the water.
Basic characteristics of various other alkali planet metal hydroxidesCa(OH)2 - basic and dissolve in overabundance water. If ion concentration increases, deposited together a white precipitate. Sr(OH)2 , Ba(OH)2 - strong bases
Basc characteristics of alkali earth metals" hydroxides boosts when going down the group.
BaO and Ba(OH)2
BaO conveniently dissolve in water to kind Ba(OH)2 colourless solution.
What room the other solid bases?
All alkali metals" hydroxides are strong bases. From alkali planet metal hydroxides, Sr(OH)2 and Ba(OH)2 are strong bases
Questions asked by Students
Ask her Chemistry Question
Is Ba(OH)2 a strong base 보다 Sr(OH)2?
Solubility that Ba(OH)2 is much greater than Sr(OH)2. So an ext OH- amount have the right to be given by Ba(OH)2 to the aqueous solution. Therefore, Ba(OH)2 is a strong base than Sr(OH)2.
Is barium hydroxide mountain or base?
See the dissociation of barium hydroxide in the water. You can see, hydroxyl ion (OH-) are given to water from it. Then OH- concentration increses an ext than H3O+ concentration. So that proves barium hydroxide is one acid.
