Zachary Kmieciak Prof. Paul / Mr. Songpo Guo Chem. 112 – 8 AM Lab September 13, 2006 Chemical Proportionality: Carbonate and Hydrochloric Acid Introduction The purpose of this lab is to investigate what occurs when a solid substance, a metal carbonate, is added slowly to a solution of acid. At the conclusion of this experiment, I will have the experience with recognizing some early observable changes that signal a chemical reaction. The chemical formula is: Na 2 CO 3 (s) + 2HCl(aq) => 2NaCl(aq) + CO 2 (g) + H 2 O(g) Procedure 1) Pour about 2 tablespoons of Na2CO3 into a watch glass and weigh. Record. 2) Pour about 10 mL of HCl .3 N into a beaker. 3) Add a drop of the indicator into the beaker. 4) Add and twirl just enough Na2CO3 from the watch glass into the beaker to turn the solution pink. 5) Weigh the watch glass and subtract to find the mass of Na2CO3 poured into the beaker. Record.
