Acids And Bases Buffer Calculation Past Paper Questionпѕњa Tldr the video script is a detailed walkthrough of a buffer calculation question from an aqa a level chemistry past paper. it emphasizes the importance of starting with moles and understanding the equilibrium shifts when adding a strong base or acid to the solution. Answer: mixture of naclo 4 and hclo 4 is not an example of an acidic buffer solution. q4. a buffer solution is a mixture of. (a) weak acid and strong base. (b) strong acid and weak base. (c ) strong acid and its conjugate base. (d) weak acid and its conjugate base. answer: (d) buffer solution is a mixture of a weak acid and its conjugate base. 4.3 test (mark scheme) more exam questions on 4.3 acids and bases (mark scheme) 4.3 exercise 1 bronsted lowry theory. 4.3 exercise 2 ph calculations. 4.3 exercise 3 buffer solutions. 4.3 exercise 4 titrations and indicators. answers to 4.3 exercises. click here to view some great books which can aid your learning. note: all resources on. One mark for ph = 0.92 or ph = 5.15. (using incorrect ka values) examiner’s comments. most candidates could calculate the ph of a weak acid although a significant number gave the answer as 3.0, presumably confusing the demand for two decimal points with two significant figures. n(c2h5cooh) = (0.0800 ×. b i. and.
