What is the 95% confidence interval for the mean of the data, assuming(a) No prior information about the precision of the analysis?(b) s → σ = 0.056 mmol Ca/L?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?1. Differentiate the following terms. Accuracy Precision 2. What are the advantages of using the analytical balance in analytic chemistry? Enumerate at least two then explain each. 3. What are the factors affecting the discrepancies in accuracy and precision? Enumerate at least four then explain each.
