Periodic Trends in Reactivity
Purpose: To explore the reactivity trends of metals in groups and periods of the periodic table.
Purpose: To explore the reactivity trends of metals in groups and periods of the periodic table.
Pre-Lab Questions:
1. The groups of the periodic table are the vertical columns. The periods of the periodic table are the horizontal rows. The groups of the periodic table that share a lot of similarities with all of the other elements in the group are families.
2. All of the metals are located to the left of the metalloid boundary.
3. Two metal families are the Alkali metals and the alkaline earth metals.
4. Gallium is in the group 3 in the 3rd period.
Procedures
Part 1: Trends in properties within groups.
1.) acquire a test tube rack
2.) acquire two clean test tubes
3.) label your test tubes
4.) fill a beaker with test water and grab a disposable pipet
5.) bring your test tubes to Charlene to get samples of magnesium and calcium
6.) use pipet to cover the sample with water
7.) observe reaction carefully and enter data in data table
8.) dump sample into hand over sink, drop sample in sample beaker, wash test tube
Part 2: Activity Series of some metals in HCL
1.) acquire 1 more clean test tube (total: 3)
2.) label test tubes
3.) 1 person goes to Charlene to get HCL from Charlene
4.) reuse magnesium, 1 person goes gets zinc and tin from Charlene
5.) cover sample with dilute with HCL adding drop by drop
6.) observe reaction and fill in data table
7.) bring samples to fume head, pour samples one by one into labeled waste bottle
