Sr(OH)2 will dissociate into what ions with what charge
Vinil7 [7]

Answer : Sn(OH)_2 will dissociate into strontium ion, Sr^{2+} with a (+2) charge and hydroxide ion, OH^- with a (-1) charge.

Explanation :

As we know that when strontium hydroxide, Sn(OH)_2 dissociates then it gives strontium ion, Sr^{2+} and hydroxide ion, OH^-.

The dissociation reaction will be:

Sr(OH)_2\rightarrow Sr^{2+}+2OH^-

Sn(OH)_2 will dissociate into strontium ion, Sr^{2+} with a (+2) charge and hydroxide ion, OH^- with a (-1) charge.
