Both of these questions can be answered with a basic knowledge of chemistry.
1. Carbonate or bicarbonate ions fizz when an acid is added (HNO3, HCl, CH3COOH, etc) and fizzing is due to the release of carbon dioxide, CO2. The reaction with HCl is
Na2CO3 + 2HCl ==> H2O + CO2 + 2NaCl for the molecular equation. The net ionic equation is
CO3^2- + 2H^+ ==> H2O + CO2
2. You need to know the solubility rules to answer this question. The solubility rules tell you that AgCl, AgBr, and AgI are insoluble. The reaction is
Ag^+ + Cl^- ==> AgCl
Hi! I really really need help in this question:
what observation is expected when:
1. an acid (nitric acid, HNO3) is added to a solution containing carbonate or bicarbonate ions?
2. silver ion is added to a solution containing chloride (or bromide or iodide) ions?
Please help and explain i have no idea what this is. thank you very very much!
