Late Nite Labs Description / WHF Textbook(s)Density – A Characteristic Property
In this lab, students will measure the density of four substances: water, ethanol, aluminum, and iron. They will use a balance to find the mass of each substance, and the technique of water displacement to measure the volume of each substance. /

Chemical Reaction Types and Their Equations
In this lab, students will perform four classes of chemical reactions: synthesis, decomposition, single displacement, and double displacement. After performing these reactions, students will identify the products of each reaction and write a balanced chemical equation for each reaction. /

Molar Mass of Magnesium
This lab assumes that students do not know the atomic or molar mass of magnesium. Students will have to measure the number of moles without simply dividing the atomic mass of magnesium by its molar mass. Instead, other methods will be used to determine molar mass. /

Limiting Reactant and Excess Reactant
In this lab, students will combine solutions of copper sulfate and sodium sulfide to produce copper sulfide (a black, solid precipitate). The two reagents will be combined in various ratios so that either copper sulfate or sodium sulfide will be the limiting reagent. /

Mole to Mole Relationship Between Cu and Ag
In this lab, students will carry out a reaction between metallic copper atoms and silver ions. The reaction will occur in solution, producing copper ions and metallic silver atoms. After the reaction, students will determine the molar ratio between silver and copper in the reaction and write an equation for the reaction. /

Stoichiometry by Loss of Carbon Dioxide
In this lab, students will do several trials in which she varies the amount of sodium carbonate added to react with a fixed amount of sulfuric acid. Students will plot the number of moles of carbon dioxide versus the number of moles of sodium carbonate used, and will use this data to determine the stoichiometric equivalence point. /

Stoichiometry of and Acid-Base Reaction
In this lab, students will examine the stoichiometry of a reaction between hydrochloric acid and sodium carbonate to yield 3 products: sodium chloride, carbon dioxide, and water. /

The Temperature Dependence of Salt Solubility
In this lab, students will determine the solubility of salt potassium chloride in water at various temperatures. Results will be used to create a solubility curve for potassium chloride in water as a function of temperature. This experiment will be repeated with several samples of ammonium chloride.

Law of Conservation of Mass
In this lab, students will investigate theLaw of Conservation of Massby studying two chemical reactions in closed systems. One reaction will take place entirely in solution, while the other will involve the generation of a gas product. /

The Enthalpy Change of a Chemical Reaction
In this lab, students will measure the heat generated by an exothermic reaction between magnesium and hydrochloric acid. Students will determine the absorption of heat by water as well as the absorption of heat by a calorimeter, and will use this data to calculate the total heat of reaction. /

Identifying Halide Ions
In this lab, students will identify halogen ions by their property of reacting with reagents to yield insoluble products. The following will be combined: fluoride ions with calcium to form insoluble calcium fluoride, iodide ions with silver to form an insoluble salt, bromide ions with silver to form a yellow insoluble salt, chloride ions with silver to form a white-silver insoluble salt. /
