Instructions and Assignment to complete
Overall Directions:
1. Read the lab assignment
2. Complete the tutorial
3. Use the directions in this document (see below) to help guide you in your lab. Watch the vimeo
video if you need a visual explanation.
4. Complete THIS document as your assignment and submit to the dropbox.
Objectives:

Distinguish between transition metals and other metals
Observe chemical and physical properties of transition metal ions in solution
Observe the results of mixing ammonia and hydrochloric acid with metal ions
Compare the reactions of transition metal ions with those of other metal ions
Lab Directions:
1. Determine the type of metal (Alkali Metal, Alkaline Earth Metal or Transition Metal) for each
metal used in this lab. (2 points)

2. Place 10 drops of the first metal (KNO3) into each well 1a, 1b, 1c
3. Place 10 drops of the next metal (Ca(NO3)3) into each well 2a, 2b, 2c
4. Continue placing 10 drops of each metal into the first 3 wells of each column on the microplate
until you have added all of the metals into their columns.
5. Add 10 drops of NH4OH (Ammonium Hydroxide, a base) to each well in Row A
6. Stir each well with a stir rod. Use a CLEAN stir rod for each well.
7. Add 10 drops of HCl (Hydrochloric Acid, an acid) to each well in Row B
8. Stir each well with a stir rod. Use a CLEAN stir rod for each well.
9. Row C is your control, do NOT add anything else to row C. This row should only have the metals
in it.
10. Use the hand lens to observe each well. Record your observations in the data table. Compare
wells A and B for each metal with the control in well C.

color change or formation of bubbles. (8 points)

Analysis:
1. Based on your observations, LIST which CHEMICALS (not well #’s) resulted in a chemical change.
Write the type of metal involved in each chemical change. 4 points
2. Based on your observations, LIST which CHEMICALS (not well #’s) did not result in a chemical
change. Write the type of metal involved. 4 points
3. In a complete sentence, make a statement about what type of metals resulted in a chemical
change. Is this what you expected? Why or why not? (Note: the reactivity in this lab is NOT the
same as the general trend of reactivity for metals.) 2 points
