Tips for Running Reactions

Be sure to combine reagents in the appropriately labeled area of the chart. This will avoid confusion

Each cell of the chart is half black and half white. Try to center the reaction on the dividing line. Having both a dark and a light background behind your reaction will make it easier to see the variety of gasses, precipitates, and colors that form

To run a reaction, add a couple drops of the first reagent, then a drop or two of the second. Be sure not to touch the tip of the microburette to other solutions or the plastic. You may need to add another drop of one solution or the other, and you can stir with a small stirring rod (be sure to rinse this with distilled water and wipe dry between uses)

To clean up an individual reaction, use an extra microburette to suck up the reaction and then discard it into a waste beaker. Then use a cotton swab to clean and dry the area.

If you want to clean off the entire sheet, add some water and pour the entire mixture into your waste beaker. Rinse well with deionized water and dry with a paper towel.

 

Be sure to take very careful observations. You probably can't be too specific! You'll need this information later, so it is very important to write down thorough observations.
