The teacher mixes an acid and a base. This can be used as a starting point for discussion of several chemistry concepts including pH, equilibrium shift, and neutralization.

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.

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.

Students will determine the percentage of phosphorous in a sample of fertilizer, using gravimetric analysis.

Students will analyze a tablet of Vitamin C and calculate the percentage of ascorbic acid present in the tablet, through titration with sodium hydroxide to form sodium hydrogen ascorbate.

Students will use titration method to determine the amount or concentration of an unknown substance. They will analyse a number of commercial products and, in some cases, test the validity of the information given on their labels.

Students will conduct two separate redox titrations using a standardized permanganate solution. In the first titration, they will be trying to find the % hydrogen peroxide in a commercially-sold solution. In the second titration, they wil find the % iron in an unknown iron salt.

Students will investigate the effects of temperature and concentration upon the position of equilibrium in a solution of cobalt (II) containing excess chloride ions.

Students will conduct a decomposition reaction and then calculate the percent composition of oxygen.

Sudents will determine the rate equation for the reaction of potassium persulfate with potassium iodide. Note: This activity requires advanced mathematical skills - logarithmic form.

Students will observe the reaction between zinc metal and dilute sulfuric acid, with and without the addition of a copper catalyst.

Students observe the effect of electrolysis of aqueous silver nitrate solution using an inert (platinum) anode and silver cathode.

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.

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.

Students will determine the equivalent weight of an unknown acid by using a standardized solution of NaOH and titration methods.

Students will determine the empirical formula of a hydrate. From the data collected the number of molecules of hydrated water will be determined per molecule of anhydrous salt.

Students will use a temperature probe, a pressure sensor, and an air sample in a stoppered flask to study the relationship between gas pressure and temperature. Note: Implementation of this activity requires a TI graphing calculator and Vernier probeware.
