Explain the following statement: The validity of an analytical result ultimately depends on knowing the composition of some primary standard.
I. Chapter 4: Chemical Quantities and Aqueous Reactions a. Section 4.1: Climate Changing (Not required for exam, just informational) b. Section 4.2: Reactions Stoichiometry i. Stoichiometry: The numerical relationship between chemical amounts in a balanced equation ii. Objective: Calculate mass relationships using balanced chemical equations 1.
