✔ 最佳答案
The answer is "Yes" in both cases.(1) Both metal carbonates and hydrogencarbonates can react with dilute HNO3 to give a metal salt, H2O and CO2,
i.e. 2H+(aq) + CO32-(aq) ---> H2O(l) + CO2(g)
H+(aq) + HCO3-(aq) ---> H2O(l) + CO2(g)
(2) Both metal carbonates and hydrogencarbonates will react in the same way, but at a higher rate in conc. HNO3. There are NO redox reactions between carbonate ions and nitrate ions.
