Ace your A Level Chemistry
Ace your A Level Chemistry exams with this in-depth analysis of a past paper question. I break down the complexities and guide you through every step to ensure you understand and can replicate them in your revision and exams.
This video is intended to be an ultimate guide on how to answer any acids and bases buffer solution calculation question you may come across under the acids and bases topic. This question is from AQA A Level Chemistry paper 1 2017 and involves a buffer calculation, which can be solved using mole calculations, Ka and pH expressions, rearranging equations, and principles of buffer solution equilibrium. This 6-mark question focuses on adding a strong base (alkali) to a solution of a weak acid and its salt. Keep in mind that if you add a solid base, you will need to follow a different method to this.
