MODEL CHEMLAB EXPERIMENT: CATION AND ANION
“ THE CHEMISTRY REACTION”
The purpose of this experiment is to demonstrate a double replacement reaction of ionic compounds. We will be demonstrating
The reactions of ionic compounds that are supposedly soluble in water, If a reaction should occur during this experiment, then
one of these ionic compounds are identified as not being soluble in water and a precipitate will occur. We may ask ourselves,
what is ionic compounds?, Ionic compounds simply are where two or more ions are held next to each other by electrical attraction.
One of these ions have an positive charge (cation +) and one will have a negative charge (anion -). Let’s experiment and observe
Whether these ions will have a reaction or indeed soluble in water.
Let’s begin this experiment by obtaining a 100ml beaker from our equipment tool bar list, then we are going to add 50ml(s) of Potassium
Chromate 1M solution to that beaker, The next step we are going to add another ionic compound of 50ml of Lead (11) nitrate 1M
into the same beaker as the Potassium Chromate. As we observe the beaker, we notice a reaction has occurred and a precipitate has formed
and settled on the bottom of the beaker. The next step is we are going to filter the resulting precipitate into a 250 ml Erlenmeyer Flask
with a Buchner funnel. Now that we have filtered the precipitate, we will then place the resulting precipitate into a test tube to measure the
By using the information above in our experiment, we were then able to determine that one of these ionic compounds are not soluble in
Water and in turn, produced a resulting precipitate which is the evidence that a reaction has occurred. We then identified the anion and
cation for these ionic compounds. The Potassium Chromate- Potassium being the cation and Chromate being the anion, then with Lead would be a cation as well, and...
