Question

Is calcium hydroxide a strong alkali? if no, why? if yes, why? i really don’t understand

Answer 1

Calcium hydroxide
`\sf \: Ca(OH)_2` is a really strong alkali or base since it has the power to accept proton when added to a solution.. Its pH is 9 and we know that when the pH is more than 7 it is a base..

One more reason why calcium hydroxide is a strong alkali is that it dissociates completely when added to any solution...

Answer 2

Yes

Step-by-step explanation:

Neither Calcium nor hydrogen nor oxygen are alkali metals

• Alkali metals are Group 1 elements
• They are very soft and mellable.
• H,Li,Na,K,Cs,Fr are included in it however H is not a actual member

Here

Ca(OH)_2 is the compound

Vant Hoff factor is 3

As it's greater than 1 it's a very strong base .

The pOH of this comes around 1.5 to 1.3

So very heavy ionic dissociation

Strong Alkali
