the unlabeled reagent bottles contain sodium carbonate, calcium carbonate, barium sulphate, sodium chloride and sodium sulphate, how with distilled water, dilute HCl and barium chloride solution can determine what is in which reagent bottle.Show with reactions with aggregate states.i know all reactions but how to know what is for what and which white solution is for carbnate or barium...can someone explain me or solve this exercise i would be so grateful

What happens if you Add to all samples HCl.
In Two samples you will observe something.
What happens if you add only water.

In carbonates will be co2 that means bubbles but how i can know where is ca where na

What happens to these two samples if you add only water?
Ca easily to find.
