Periodic Relationships Virtual Laboratory Portion

Periodic Relationships Virtual Laboratory Portion

College Chemistry

​Part 1 .

• This portion will be completed in the lab.

• ​But pictures are provided for each reaction for students that are absent.

• ​Keep in mind that if a reaction occurs it means the metal is more reactive than the metal in solution.

• ​If no reaction occurs then the metal already in solution is more reactive than the loose metal.

• ​Use your information to place these metals in order from least to most reactive.

​Part 1 . Experiment 1

• With your observations notate the changes in these pictures over time. In this example notice that the liquid begins to turn blue while a precipitate forms on the outside of the wire.

​​This means that copper is more reactive than silver. It was able to kick it out of solution.

​Part 1 . Experiment 2

​No change occurred in this experiment

​Part 1 . Experiment 3

​I didn't get a great "before" picture. I added this to make sure you understood the solution started out blue.

​Part 1 . Experiment 4

Here is an online example and then on the right is what we saw in the lab. It came out really fuzzy.

​Part 1 . Experiment 5

​We saw no reaction in this test

​Part 1 . Experiment 6

​This reaction caused bubbles to form and black streaks on the magnesium

​Part 2 will be completed while viewing the attached video

• Here we can assume if a reaction occurs the metal is more reactive than hydrogen which acts like a metal due to it's nature to be a positive ion. The rate of the reaction will play a part in this experiment so be sure to note it in your observations. Once gain you will rate these from least reactive to most reactive.

​You can make the video full screen. Ignore Tin (Sn) and Iron (Fe).

​Part 1 . Experiment 7

​This experiment showed no reaction

​Part 3 will be completed while viewing the attached video

Use this video to make your observations about Zinc (Zn), Magnesium (Mg), and Calcium (Ca).

​You can ignore the other metals. Feel free to fast forward but the narration is helpful.

​Part 3 will be completed while viewing the attached video

Use this video to make your observations about Sodium (Na) , Potassium (K), and Lithium (Li).

​

​Part 4 will be done in class but this video can be used to rewatch magnesium.
