Experiment

You have learned the techniques you need to perform this determination during

your earlier labs. Consult those procedures and your results to help in planning

your experiments. Before you begin your experiments, you need to devise an

experimental plan and procedure for what you will do.

This is a two-week lab. You will come up with the plan during the first laboratory

session and start to carry out experiments. You will finish the experiments in the

second week and write up your conclusions.

Remember that all conclusions need to be supported by evidence! For

determining the identity of the salt make sure to rule out all other choices. For

determining the concentration of the salt make sure to make at least three

determinations so that you have a sense of the uncertainty in your

measurement.

Available Materials

In addition to what you have in your lab drawer, you will have all the lab

equipment from the first four labs available to you for this experiment. You do

not need to use and should not use all the equipment in the lab.

Data Collection

When collecting data, keep everything well organized and labeled. Think about

the experiments you will perform. What data will need to be recorded? Set up

tables for yourself to help in organizing your data.

Safety Considerations

Talk through your experimental approach with your laboratory instructor before

beginning to make sure you have appropriately accounted for safety. Check

safety considerations from previous labs to aid in developing your approach to

completing this lab safely.

Waste Disposal

Dispose of solid waste in the appropriately labeled solid waste container. Dispose

of liquid waste in the appropriately labeled liquid waste container.
