Short writeup:
This is easily one of my favorite H2 Chemistry Paper 4 set in 2023. It's not necessarily the best but it appeals to me a lot.
The biggest strength in this paper is it's insightfulness. The titration question seems easy on the surface but requires a deep level of thinking in order to fully comprehend the lessons behind the question. It challenges a student to think even after completing the lab session. In fact, the more you think about it, the more confused you get.
The rest of the experiments in the paper are not too difficult. Most students would expect to see such questions in their A level paper based on their teacher's experience and inputs. Many students would find this paper within their expectation and few would be taken aback upon going through the paper.
All in all, a good paper to review with an experienced mentor and few would benefit without the appropriate guidance.
