Experiment: Ionic Reactions
Lab partner: None
Location: My house
Date Performed 19 Mar 15; 0800
The goal of this experiment was to work with Ionic substances. The purpose of this experiment was to study and apply the nature of ionic reactions, write balanced equations, and gain a detailed view of the results of the reactions. In this lab we were able to identify some of the characteristics of anions and cations. I was a able to successfully perform the flame test to identify cations as well as identifications of the anion reactions of an ionic compound.
Experiment and Observation:
Please note that this procedure was adapted from the “Anions, Cations, and Ionic Reactions” LabPaq Lab manual (Hands-On Labs Version 42-0304-82-00-01, 2015) Please reference this manual for further information on the lab experiments.
The first experiment was to perform a qualitative anion test. This was done by observation of chemical reactions and recording the results in Data Table 1. Using the information from the reactions we were able to identify unknown substances and recorded the results in Data Table 1.
