Chemistry 2.1 Quantitative Analysis Internal 4 credits

Carrying out an acid-base titration that: Collects titration data with at least three titre values that fall within a range of 0.2 mL; Has average titre value within 0.2 mL of the expected outcome. Uses only concordant results.

Processing both primary and secondary data to solve quantitative problems that: Use the relationships n=m/M and c=n/V to calculate one variable given the other two. Involve more than two steps, Involve the use of stoichiometric principles. Are carried out correctly using only concordant titre values. Demonstrate correct units and appropriate use of significant figures.
