This is my second O Level SPA and according to my school, the topic is...
"Stoichiometry"
Anyone who has taken SPA before knows what can fall under this topic?
It's a very broad topic and I can't really tell what falls under it...
You may want to ask your graduated seniors as they may have some clues.
Usually, the experiements are on titrations. But as you say, this is a broad topic.
You may like to go through the SPA practices the teacher has gone through. Usually it is quite similar to the practices. Recall any clues the teacher may have given. You may also like to ask your schoolmates from other classes.
