Calcium is an essential nutrient in our body. It is important for bone health. Four common calcium-containing supplements are calcium carbonate $\left(\mathrm{CaCO}_{3}\right),$ calcium citrate $\left(\mathrm{Ca}_{3} \mathrm{C}_{12} \mathrm{H}_{10} \mathrm{O}_{14}\right)$ calcium gluconate $\left(\mathrm{CaC}_{12} \mathrm{H}_{22} \mathrm{O}_{14}\right),$ and calcium lactate $\left(\mathrm{CaC}_{6} \mathrm{H}_{10} \mathrm{O}_{6}\right)$. Rank these calcium supplements in terms of the mass percentage of calcium they contain.
What is the role of calcium in bones? In muscle contraction?
One commercially available calcium supplement contains calcium gluconate. Look up the formula for calcium gluconate. Identify the charges on the calcium and gluconate ions. Are the calcium and gluconate ions monoatomic or polyatomic? Explain.
