[S4 Chemistry PMCians]
What we did in 2 hours:
We explored electrolytic cells with reactive electrodes (lose mass only at positive terminal!), how electrolysis is applied to electroplating/ purification of metals and simple cells. We also recapped on the important thought processes to analyse electrolytic cells.
What you take home:
We are nearing the end of the chapter (yay!). With our current understanding of the chapter, you should be able to attempt all remaining questions in the Take Home Gems package.
We will complete our chapter on electrolysis with a quick-fire quiz next week. We will also consolidate our learning this year with a Topic Mastery Quiz on Speed of Reaction, Energy Changes & Electrolysis. Do start your revision!
As the weighed assessment season approaches, we would like to assure you that PMC is here to support you in every step of the way. Feel free to snap us a picture or drop us a message to clarify any doubts (and ask for tips) you may have with your revision and we will get back to you as soon as we can!
