Hello! We're back again!:D
For this week, we carried out an experiment for Colloid Chem which is to test the stability of 2 types of colloids, that is the Gelatin colloid and Hydrated Iron(III) oxide colloid~
Here's a picture of the gelatin colloid which hasn't been destabilised yet. Looks clear right?:)

Now, here's how a destabilised gelatin colloid looks like. It's looks turbid just by the addition of approximately 1mL of ethanol;)
Next, here's how hydrated iron(III) oxide colloid looks like when it hasn't been destabilised yet:)
