chemical properties of salt

1. React with metals

[Review] The phenomenon of the reaction between iron wire and blue copper sulfate solution and the reaction between copper wire and silver nitrate,

[Review] Please write down the equation for producing CO2 in the laboratory.

[Discussion] Based on the above reaction, can Na2CO3 and NaHCO3 react with dilute hydrochloric acid? If they can react, what substances will they produce?

2. React with acid

【Experiment 11-1】Can sodium carbonate and sodium bicarbonate react with hydrochloric acid to produce CO2?

To sum up: Salts containing carbonate ions (CO32-) or bicarbonate ions (HCO3-) can react with hydrochloric acid to produce CO2 gas.
