Hi! There…

First off, Ms.K. gave us a sheet entitled IDENTIFICATION OF UNKNOWN SOLUTION; this sheet explained the step by step process in identifying an unknown solution. Like....
Carefully observe the unknown solution (colour) .....
- Some Aqueous solutions can be recognize by their colours such as the Copper (blue),Chromium(green),iron( pale yellow) etc.
Observe according to their solubility.....
- This can be recognize by mixing the solution to other solutions, be sure to list the products or the outcome (whether they precipitate or not), this may be helpful in identifying the unknown compound.

After she went over the sheet, she let us to choose our partner and gave each pair a four different types of unknown solution (*different in each pair). And the only equipment that we’d used to identify the unknown solution are the following: spot plate, stir stick, a solubility chart and the solution themselves.

This experiment must be done meticulously to avoid any mistakes.....!*_*

All solutions were in dropper bottles, where you just need to add a few drops of an assign unknown solution from the dropper bottle to the plate. Observe if the solution precipitates or the colour changes(list your observation). Repeat the process from the rest, Remember that all the observation you came out with ,are very helpful in identifying the unknown solutions.

So,that's all for today........

the next scribe will be hmmmmm...Ramina!:>
