Lab report format, types of reactions, elab: diffusion across a semi-permeable membran.

Purpose: Explore how the identity of reactants and products can be used to classify types of reactions.

Question: How does knowing the reactants and products help you classify a chemical reaction?

MATERIALS AND PROCEDURES

Materials: (list all the supplies include names and quantities) Bunsen Burner Striker Tongs Test Tube Test Tube Rack Test Tube Holder Spatula Sandpaper Transfer Pipette Tweezers Evaporating Dish SUBSTANCES: Copper Wire, Sodium Carbonate, Copper Sulfate, Potassium Iodide, Lead Nitrate, Zinc

Grab a testing tube and your pipette and put 20 drops of copper sulfate into the tube. Then hold up zinc next to the sulfate, and record the texture appearance, etc... of the reactants. I expect a double replacement reaction from this reaction.

Put the Zinc into the Copper Sulfate and give it a few minutes to react. Then record the reaction. Instead of a double replacement reaction, I got a single replacement reaction, copper, and zinc sulfate out of this reaction.

Next, grab another testing tube and put 10 drops of potassium iodide. Next you grab yet another testing tube and put 10 drops of lead nitrate. Then record the texture, appearance, etc... of the reactants. I expect and double replacement reaction from this reaction.

Next, add the lead nitrate to the potassium iodide and record the reaction. Then, record the reaction. I did indeed get a double replacement reaction from the reaction, and lead iodide.

Next, prepare a copper wire. Use sandpaper and sand the wire down until it is shiny. Now record its appearance, texture, etc... I expect a Oxidation Reaction.

Next, grab a Bunsen burner and turn it on. Then use metal tongs to hold the wire in the hottest part of the flame. Hold the copper wire there for 2 mins. Now, record the reaction. Instead of a single replacement I got a combustion and synthesis reaction (pretty sure this is an oxidation reaction as well, I’m writing this at 3 am, so I can brain rn) , oxygen gas, and copper oxide.

Next, grab another testing tube and keep your Bunsen burner in reach. Then, use a small spatula to place about half an inch of sodium carbonate in the tube. Then record
