1. Purpose: To detect the unknown concentration of KMnO4.
2. Theory: It is a technique used to find the unknown concentration of substance, which has the
tendency to interact with electromagnetic radiation (light).

1. Purpose or objective: to see how accurate and precise our measurements are, as
well as to learn about the rules of significant figures, and to learn to calculate the
mean, deviation, standard deviation, range and median.

1. Purpose or objective: to detect the percentage of sodium hypochlorite (NaOCl) by titrating the
bleach against a standard reducing agent sodium thiosulfate (Na2S2O3). As well as to detect the
weight percent of H2O2 in the commercial hydrogen peroxide so
1. Purpose or objective: to determine the unknown mass of a sample of ammonia oxalate monohydride by dissolving this mass and titrating it with a standardized solution of potassium
2. Theory: to be able to determine the end point (by detecti
Mole-Mass and Mole-Volume Relationships
molecular oxygen (O2) molar mass is 32.0 g/mol
oxygen atoms (O) molar mass is 16.0 g/mol
molar mass = 1 mol.
Avogadros hypothesis states that equal volumes of gases at the same
temperature and pressure contain equal
The Mole: A Measurement of Matter
matter is composed of atoms, molecules, and ions
A mole (mol) of a substance is 6.02 1023 representative particles of that
substance and is the SI unit for measuring the amount of a substance
Avogadros number: 6.02 102

Unit 4 Thermochemistry
This unit introduces the concept of energy in chemical reactions. The topic is called
Thermochemistry because energy often enters or leaves a system as heat. Since the
science of chemistry is very concerned with how mat
