What does the equilibrium equation between solid calcium carbonate and its solvated ions describe?
- The concentration of calcium ions in a saturated solution
- The ratio of solid calcium carbonate to its ions in solution
- The establishment of equilibrium in an aqueous solution with calcium and carbonate ions (correct)
- The precipitation of calcium carbonate
What happens if the reaction quotient, Qsp, is less than the solubility product, Ksp?
What happens if the reaction quotient, Qsp, is less than the solubility product, Ksp?
- No precipitation will occur (correct)
- Equilibrium is established
