Chemistry Labs
Late Nite Labs Description
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.
Charles’s Law
In this lab, students will test Charles’ Law by varying the
temperature of a sample of gas and measuring the
corresponding change in volume.
Boyle’s Law
In this lab, students will test Boyle’s Law by varying the volume
of a sample of gas and measuring the corresponding change in
pressure.
Avogadro’s Law
In this lab, students will test Avogadro's Law by measuring the
number of molecules in 100 mL samples of different gases.

Using the average of the number of molecules in the gas
samples, students will compare the results with the Ideal Gas
Law.
Characteristic Properties – Melting Points and Boiling Points
In this lab, students will identify four unknown liquids by
observing and measuring the melting point and boiling point of
each liquid and comparing these numbers to known literature
values.
Law of Conservation of Mass
In this lab, students will investigate the Law of Conservation of
Mass by 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.
Titration of Strong and Weak Acids
In this lab, students use both an indicator as well as a pH meter
to determine the endpoint. Use of a spectrophotometer and
conductivity meter in detecting the endpoint are also discussed.
Buffers
pH Indicators
In this lab, students will examine several different pH indicators.
students will dilute solutions of hydrochloric acid and sodium
hydroxide with water to produce solutions with a range of pH
values. Students will then identify the most effective pH
indicator for the each pH range.
