NaHCO₂ (s) is commonly called sodium bicarbonate or baking soda. When NaHCO, is heated above 110 °C, but not heated to excessively high temperatures, it has been observed that both H₂O(g) and CO₂ (g) are evolved by some chemical change, and that after this decomposition reaction is complete, a white solid residue remains. Among possible reactions, the two following unbalanced reactions seem the ones that are most likely to explain these facts: NaHCO() sodium bicarbonate NROO() sodium bicarbonate Na₂CO₂ (s) sodium carbonate Na₂O(a) sodium oxide H₂O(l) water vapor H₂O(1) water vapor + Cos) (Reaction A) carbon dioxide carbon dioxide (Reaction B) How can we decide which of the two possible reactions is the one that actually occurs? What is the identity of the white solid? Is it sodium carbonate or sodium oxide? You are to choose between reactions (A) and (B) on the basis of your laboratory results, which will involve heating a weighed sample of sodium bicarbonate in a crucible and weighing the residue left in your crucible after heating. From the mass of the solid product, you should be able to decide if the product of the reaction is Nayo (s) or Na2CO3(s).
