Lab

Limewater Investigation

I will notice that when a chemical reaction occurs, the atoms of substances (reactants) rearrange to form new substances (products).


First things first

First things first…

  • Reactant: a starting substance in a chemical reaction

  • Product: a substance produced in a chemical reaction

  • Example:

HCl + NaOH H2O + NaCl

Reactants

yields

Products


Procedures

Procedures

  • Put on protective eyewear.

  • Put both pieces of rubber tubing on the same piece of rigid plastic tubing. Like shown in the diagram at the end of the directions.

  • Using the syringe, measure 30mL of limewater. Pour limewater into the plastic bottle.

  • Seal the bottle with the rubber stopper, making sure that the smaller of the 2 flexible tubes is inside the bottle.

  • Take turns using your straw mouthpieces to gently bubble one breath of air into the bottle through the longer of the plastic tubes.

  • Repeat step 5 until everyone in your group has had two turns.

Clean up

Clean Up

  • Rinse syringe with water

  • Throw away straw pieces.

  • Detach rubber stopper from bottle and empty the bottle contents into the sink.

  • Use the vinegar/acid wash in your bin to swish away any left over residue in the bottle.

  • Return the vinegar/acid wash to the vinegar bottle in your bin.

  • Rinse the plastic bottle once more with fresh water from the sink.

  • Put cleaned (&dry-ish) supplies back in your bin.


Results conclusions

Results & Conclusions

  • Describe what changes you observed in the bottle.

  • Starting substances change into new substances during chemical reactions. Do you think a reaction occurred I the bottle? Why or why not?
