The whole concept of calculation Ksp and such is really confusing me. Im working through the destoyer and in some questions you only use the coefficient of the reaction as exponents in others you use them as exponents and multiply the whole expression by it. I know this is unclear let me give an example`
Q: Consider Calcium Phosphate, what is the calcium concentration if the Ksp = 2x10-30
the answer is 3^root3 of (2x106-30/108) which means they did
Ca3(PO4)2--> 3Ca + 2PO4
ksp= [3Ca]^3 [2PO4]^2.. why is it this expression and not ksp= [Ca]^3 [PO4]^2
Ive seen discrepancies like this in the common ion effect problems too. Im so confusedd!!! Thanks for any help!!!
