A student attempted to identify an unknown compound by the method used in this experiment. She found that when she heated a sample weighing 0.4862 g, the mass barely changed, dropping to 0.4855 g. When the product was converted to chloride, the mass went up to 0.5247 g. A. Is the sample a carbonate? ________ B. What are the two compounds that might be in the unknown? ______________ or ___________ C. Write the balanced chemical equation for the overall reaction that occurs when each of these two original compounds is converted to a chloride. If the compound is hydrogen carbonate, use the sum of Reactions 1 and 2. If the sample is a carbonate, use Reaction 2. Write the equation for sodium salt and then for potassium salt.
