Gravimetric Analysis of Periodic Trends
Item #: PF2020
Price: $85.00
Performance Assessment
In this lab experience, students quantitatively determine the solubility of sodium halide salts in methanol. Then they use their results to make a prediction about the solubility of sodium fluoride. Students should come to understand that periodic trends can be used to make predictions about the behavior of a material. This empowers researchers to be more efficient when developing new compounds or procedures.
