$59.99The yield of ester can be increased either by removing one of the products of the reaction as it is formed or by increasing the concentration of one of the...
Lechatelier's Principle -IS8004
$43.00Le Chatelier’s Principle is a qualitative rule, which allows the prediction of the effect of temperature, pressure and concentration changes on chemical reactions. The principle states: A chemical system at...
Mole Ratio Reactants Ap Chemistry Kit -IS8003
$39.75Using the method of continuous variation, two solutions are combined in various ratios. To select the ratio that produces the most product or consumes the most reactants, students must find...
Activity Series Ap Chemistry Kit -IS8002
$105.00An activity series of metals is a table of metals arranged in the order of their decreasing chemical activity or the ease at which the metal will give up one...
Thermochemistry & Hess Law Ap Chemistry Kit -IS8001
$45.00Employ Hess’s Law of enthalpy based on the observed data for two reactions. Students can measure the temperatures of the reaction in a calorimeter and analyze the data calculating the...
Electric Art -IS7049
$38.00A copper “pen” will be used to electrolyze a solution of potassium iodide and draw on a piece of filter paper. The color of the “ink” will change depending on...
Electrolysis Of Tin -IS7048
$21.95The electrolysis of a tin (II) chloride solution demonstrates the oxidation and reduction of Sn2+ ions as beautiful tin crystals grow and spread throughout the solution. There are enough materials...
Gold Nanoparticle Demonstration -IS7047
