I'm having trouble balancing this equation: SO3^2- --> S2O4^2- It's in a basic solution. Thanks.
Hydroxylapatite, Ca10(PO4)6(OH)2, has a solubility constant of Ksp = 2.34 × 10^-59. Solid hydroxylapatite is dissolved in water to form a saturated solution. What is the concentration of Ca2 in this solution if [OH] is somehow fixed at 5.30 × 10^-6 M?
