Which are characteristics of a primary standard? has an anhydrous form as a well as hydrated form low cost stability in the atmosphere high purity low molar mass high molar mass low solubility
Analytical chemistry is a particular field within the broader spectrum of the chemical sciences, in which many times the focus of analytical experiments is to develop new methods to analyze compounds, either structurally or by determining concentrations of compounds. One of the processes analytical chemists use to determine the exact concentration of a working solution is called standardization. In your own words, describe the differences between a primary, secondary, and tertiary standard, and describe the underlying concept behind the standardization process. Why is it done?
To determine the mass of Fe2O3 from the given mass of K3Fe(CN)6, the gravimetric factor to be used is a. Fe2O3 / K3Fe(CN)6 b. Fe2O3 / 2K3Fe(CN)6 c. 2Fe2O3 / K3Fe(CN)6 d. 3Fe2O3 / 2K3Fe(CN)6
How would each of the following errors affect the determination of the molar mass of the unknown (Increase/Decrease/No effect)? a. Thermometer reads 2.0o higher than the true temperature. b. Some of the t-butanol was unknowingly spilled after it had been weighed but before the solute was added. 3. A student accidentally added acetylsalicylic acid (MW = 180.157 g/mol) rather than salicylic acid (MW = 138.121 g/mol), if no other mistakes were made, how would this error affect the determined molal freezing point depression constant for t-butyl alcohol (Kf)? 4.
