What is the concentration of K+

ions in a 0.045 M
K2CO3
solution assuming complete dissociation?

Since K2CO3 dissociates completely in water, it will produce two K+ ions for every one K2CO3 molecule.

Therefore, the concentration of K+ ions in a 0.045 M K2CO3 solution would be 2 x 0.045 = 0.09 M.

So, the concentration of K+ ions in a 0.045 M K2CO3 solution assuming complete dissociation is 0.09 M.
