Product Details

Often times, the composition of a mixture may contain a variety of unknown components. In some cases, the components of a mixture may be known but the exact  amount of those components in the mixture is not. Analytical chemists often have a variety of tools and techniques to analyze unknown substances and arrive at conclusions with regards to the compounds/percentages in the mixture. In this activity, students will determine the percent composition of sodium carbonate and sodium  bicarbonate in an unknown sample. The mixture is heated vigorously until the sodium  bicarbonate is completely decomposed to sodium carbonate.
The only other products of the reaction are carbon dioxide and water. After performing the necessary calculations, students will determine the percentage of sodium  bicarbonate that was present in their original sample. There are enough materials for 15  groups. Teacher’s manual and student copymasters are included.

Kit Includes:
1 Sodium carbonate, 200g
1 Sodium bicarbonate, 200g
5 Pre-labeled bottles (to prepare unknowns)

Each bottle of our reagents come standard with an MSDS sheet included. If you require a copy of this prior to purchase, please contact us.
