A simple demonstration of how a precipitate is evidence of a chemical reaction taking place is performed by mixing solutions of calcium chloride and sodium carbonate to form the precipitate calcium ...

The calcium chloride [solution] tends to corrode the surface faster, because we have more chloride ions, but also has a faster rate of carbonate formation,” Perrine said, adding that in a video her ...

Sodium carbonate, Na 2 CO 3 ... The resin needs recharging with dishwasher salt (sodium chloride) once it becomes full of calcium ions.
