What is the concentration of K+K+ in 0.15 MM of K2SK2S? Express your answer to one decimal place and include the appropriate units.

Answer : The concentration of ion in 0.15 M is, 0.3 M

Explanation :

The given compound is,

When dissociates then it gives potassium ion and sulfide ion.

The balanced dissociation reaction is:

By the stoichiometry we can say that, 1 mole of dissociates to give 2 moles of ion and 1 mole of ion.

Or, in terms of concentration we can say that:

0.15 M of dissociates to give of ion and 0.15 M of ion.

Thus, the concentration of ion in 0.15 M is, 0.3 M
