Kidney stones are crystals of calcium oxalate that form in the kidney, ureter, or bladder. Small kidney stones are passed out of the body easily, but larger kidney stones may block the ureter causing SEVERE pain. If the [Ca^+2] in blood plasma is 3.2 x 10^(-2)M, what [C2O4^-2] must be present to form a kidney stone? Ksp = 2.3 x 10^(-9) x 10(-8)M (to the proper significant figures)
