Question

Quizplus · Accepted Answer

When calcium ion (Ca₂+) and carbonate ion (CO₃2-) are combined, they form an insoluble compound called calcium carbonate (CaCO₃), which precipitates out of solution. The other ions (Cl- and Na+) do not react with each other or with the CaCO₃ precipitate, so no other compounds will be formed.

If the Following Ions Ca₂+, Cl-, Na+ and CO₃2- Are
