How to Write the Lab Report Using the CER Method

Create a data table similar to the one you used while doing the lab but add a column for the

formula and another column for the name of the compound. See the sample heading below. Add

19 lines for the combinations of ions you created.

Station

Cation

Anion

Description

Formula

Name

Completely fill out the table by copying what you recorded when you did the lab then write the

correct formulas and names for each compound. This completed data table contains the

information you will use to write “E” statements for the prompt.

Select one compound from each station to address the prompt using the Claim-Evidence-

Reasoning method of writing critically. This means you will have five CER statements written

under the data table in your lab report.

The Prompt Is: Verify that ionic compounds were made in this lab. Do this for each of the

compounds you selected. Make certain to identify in each claim which cation and anion

combination you chose.

Example of a CER response:

Claim: At station X, Ca

and O

reacted to form calcium oxide which is an ionic compound.

Evidence: Two liquid solutions produced a white precipitate.

Reasoning: Ionic compounds are formed when cations react with anions. Calcium is a metal; all

metals form cations due to losing electrons. Oxide is the anion that results from oxygen gaining

electrons.
