PASCO's College Chemistry Instructor Guide is designed by chemistry educators to help teach students through guided inquiry and covers major introductory and general chemistry topics through 36 challenging experiments.
Topics covered include:
Supports effective student learning:
Use a stainless steel temperature sensor to help confirm the identity of a sample of alum synthesized in Lab 15a by conducting both qualitative and quantitative analyses.
Use a crucible and Bunsen burner to determine the water content of a hydrated salt.
Use a crucible and Bunsen burner to react a chemical with air in order to determine the stoichiometric composition of an ionic compound.
Use a stainless steel temperature sensor with gravimetric analysis to determine the amount of sulfate in a sample of an unknown alkali sulfate.
Use an absolute pressure sensor and stainless steel temperature sensor to identify an unknown metal by applying the Ideal Gas Law.
Use a conductivity sensor to determine the stoichiometric coefficients of the reactants of a chemical reaction.
Use a spectrometer to learn about the composition of the electromagnetic radiation in the visible range, to develop an understanding of how the interaction of objects and solutions with light result in the perception of color, and to dispel misconceptions of objects "having color." A spectrometer is required to perform this lab. We recommend PASCO's Wireless Spectrometer.
Use a stainless steel temperature sensor to determine the molar mass of an unknown volatile liquid at the boiling temperature of water and atmospheric pressure.
Use an absolute pressure sensor and stainless steel temperature sensor to explore the relationship between pressure and volume, and pressure and temperature, for a gas.
Use chemical reactions and chemical properties to analyze solutions of known anions, using the results to analyze a solution of unknown anions.
Use a colorimeter to learn how the factors of concentration and path length affect the absorbance of a colored solution.
Use a conductivity sensor and drop counter to determine the concentration of a solution with titration.
Use a stainless steel temperature sensor to determine the molecular weight of a compound by measuring the freezing point depression of a solution.
Use chemical reactions and chemical properties to identify the cations present in a mixture by systematically reacting the unknown with various reagents.
Use a pH sensor and drop counter to determine the molar concentration of a strong acid solution by titrating measured volumes with a strong base of known concentration.
Use a pH sensor and drop counter to determine the acidity constants of two isomeric multi-protic acids and relate the acidity constants to their structural differences.
Use a pH sensor and drop counter to determine the equilibrium constant for the ionization of a weak acid to ascertain the identity of the acid.
Use a pH sensor to demonstrate the properties of buffer solutions and buffer capacity.
Use a pH sensor and drop counter to determine the concentration of a sodium hydroxide solution by titrating it with a standard solution of known concentration.
Use a pH sensor and drop counter to determine the solubility product of an ionic compound through titration and calculations.
Use an absolute pressure sensor and stainless steel temperature sensor to determine the rate constant of a chemical reaction.
Use a colorimeter to determine the equilibrium constant for a chemical reaction.
Use a voltage sensor to determine the half-reactions that relate to the anode and cathode of a galvanic cell and to calculate the electromotive force for a battery.
Use a voltage-current sensor to construct an electrochemical cell that deposits copper onto another metal surface and to apply Faraday’s law to relate the total electric charge to the mass of metal deposited.
Use an oxidation reduction potential electrode and drop counter to determine the concentration of a commercial, nominally 3% hydrogen peroxide solution, measuring the change in potential during an oxidation-reduction reaction.
Use a stainless steel temperature sensor to synthesize an organic compound (aspirin).
Use a stainless steel temperature sensor, pH sensor, and drop counter to perform qualitative and quantitative analytical methods, including melting point determination and titration, to analyze the purity of the aspirin synthesized in Lab 22a.
