Lesson 12


Today's lab involved two types of experiments but both had the same objective. We split a compound into it's basic elements.

With the first demonstration we used electrolysis to break down H2O:
Our Findings -
- the negative current picked up the hydrogen gas and split it twice as fast as the positive current split the oxygen gas.
- there were twice as many hydrogens as oxygens as well.

Then we tried to split H2SO4 (sulphuric acid) to see if we could isolate the hydrogen gas and get it to make a massive "pop".

We did it alright!!!

So, we determined that compounds can be split into their basic elements.
