Question

Before coming to the first lab period, use your text book, your class notes, the internet, the library, and your brain to come up with a chemical equation for the reaction you plan to do in lab. The first thing you want to consider and figure out is what reactant(s) must be added to Na_2CO_3 to make the desired product. Consider what other aspects of the reaction must be controlled. In addition to determining all of the reactants that should be added, you must consider how much of each reactant should be added, whether a solvent is necessary, what glassware should be used, etc. You must also consider what byproducts will result from your reaction and how you will be able to isolate the pure NaCl that you want. Once you have an idea of what reactants you want to use and what products will be produced, write a balanced chemical equation for the reaction you plan to carry out, you will probably not get all of the necessary work done within the allotted time period. When you arrive in lab, share your ideas with your lab partners. Collaborate to create a proposal for how to perform the reaction. As you type up your proposal, create a list of all chemicals and materials you will need to use in your reaction. You must hand in a materials list via LabArchives to your TA by the end of the first lab period so that the materials will be ready for your to use when you come to the second lab period. Before you continue, check with your TA to make sure your proposal is acceptable.

Explanation / Answer

SOLUTION:

Na2CO3 is a base and you want a salt (NaCl) to prepare from it. Bases form salts upon reaction with acids. Hence Na2CO3 must be treated with an acid that contains Cl- as anion. So we can treat Na2CO3 with HCl to prepare NaCl as:

Na2CO3 + 2HCl -------> NaCl + CO2 + H2O

NOTE: This is all information you have asked for in the note. So we have given this only.
