Unformatted text preview: 3 + H + CO 2 + H 2 O + Na + 9. Distilled water should be used in the lab instead of tap water because tap water is treated with chemicals that could cause unwanted reactions in the solutions we’re testing 10. If you were to add H2SO4 to a mixture of Na2CO3 and NaCl, you would not be able to detect the presence of Na2CO3 because the H from the acid would bind with the Cl from the salt, and nothing else. 11. 12. Dissolve the mixture in water. Then, add a little silver nitrate. Silver ions precipitate with chloride ions to form silver chloride. Then you could add some acid, like a little nitric acid. The carbonate ions will react with the protons to form carbonic acid, which will decompose into CO2 gas, and make bubbles....
