Calcium oxalate (cac2o4) has a ksp value of 2.3 × 10–9 at 25°c. calculate the molar solubility of ca2+ and c2o42– in one liter of aqueous solution.
ksp = [x] × [x]
what is the molar solubility of ca2+?
2.3 x 10-9 m
4.8 x 10–5 m
4.60 x 10-9 m
5.29 x 10-18 m

Me i dont know what to do! the table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 10 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
