Acid/Base Titration of an Eggshell
Read the Fine Print
Rating
0.0 stars
Overview:

Students will explore acid/base titration using an eggshell (calcium carbonate), NaOH and HCl. During the course of the experiment, students will also calculate molarity of NaOH, moles of HCl left in solution, and percent calcium carbonate in the eggshell.

Rating
3.0 stars
Overview:

Students will attempt to react a metal with several solutions. Each of these will be a single displacement reaction. After recording data on whether a reaction occurred or not, they will be able to figure out relative reactivity for each one. Students will also write balanced equations for each reaction.

Elements, Mixtures, Compounds, Solutions, and Phases Activities Review
Read the Fine Print
Rating
0.0 stars
Overview:

Students will complete several activities. In the first, they will circulate through seven lab stations where they will be presented with elements, mixtures, and compounds. They will identify the sample as homogeneous or heterogeneous and classify the material as an element, compound, mixture, or solution. In the second, they will light a candle and examine how an element differs from a compound. In the third, they will model heterogeneous mixtures and phases.

Rating
0.0 stars
Overview:

Students will determine the activation energy of a chemical reaction. During the experiment, they will measure the rate constant for a chemical reaction at several temperatures, plot log k Vs. 1/T, and determine the activation energy of the reaction from the slope. Note: This activity requires advanced mathematical skills.
