Single Replacement Reaction Lab

Safety and cleanup will be considered part of the grade. Have your lab stamped when your station is clean. Minus 10 points every time someone in your group removes their goggles.

Some important info:

Zinc’s oxidation state is +2 Copper’s oxidation state is +2 Tin’s oxidation state is +2

PRE-LAB

  1. In the table below, write down the metals and solutions (from your lab table) you will be using.

Metal

/

Solution

LAB

  1. Set up the transparency like this:
  2. Put 1 piece of each metal across each ROW. (5 rows total)
  3. Put 1-3 drops of solution on top of each metal in a COLUMN.
  4. Look for changes as soon as you add solution, but some take longer.
  5. Record your results in the data table below. What happened in each combination? Remember to look for subtle changes as well as drastic changes, but only record chemical changes.

DATA TABLE

CLEAN-UP

  1. Re-capture any pieces of metal, rinse them with water, and place them on a paper towel to dry. You may need to clean them with a brush if they do not rinse clean.

5.  Rinse the transparency in the sink and dry it gently with a paper towel. Have your station’s cleanliness checked and signed/stamped.


POST-LAB

  1. For each reaction you observed, write a balanced chemical equation with state signifiers.
  1. Which metals started in solution and came out as solids in the reaction? (these are less reactive)
  1. Which metals started as solids and ended up in dissolved compounds? (these are more reactive)
  1. Some metals are more reactive than others. Create an activity series for the metals you observed. Using your data, place the METALS in order from most reactive to least reactive:

Observed activity series for METALS

  1. Alkali metals are very reactive and never found in nature in their pure form. Predict the outcome of the following combination and explain your answer using what you learned in this lab:

NaCl(aq) + Zn(s) ®

  1. Make a “general rule” type of statement about the circumstances under which ‘no reaction’ will occur? Do not mention any chemicals by name.
