1. The problem statement, all variables and given/known data I have found, through experimentation, the ksp of calcium hydroxide to be 3.0 x10^-7 (which i know has a pretty large percent error). However, i am conflicted as to what the units should be because logically, plugging the units into the ksp equation should give you units of M^3 (ksp= [ca][oh-]^2. However, after research online, i found that ksp doesnt have units. Why does Ksp have no units if it is seemingly so easy to calulate it? 2. Relevant equations 3. The attempt at a solution One idea i was thinking about was that the ksp units are unique to each equation which may be why they are omitted?
