Solution
It seems like your question is incomplete or not clear. If you're asking about which cations are involved in carbonate hardness, the answer is both Calcium (Ca2+) and Magnesium (Mg2+). These two cations react with carbonate (CO3 2-) and bicarbonate (HCO3-) anions to form scale deposits. Sodium (Na+) does not contribute to carbonate hardness.
