i think there's a mistake in their solution to 31, the graph is skewed in that scan so they accidentally drew the line down to 0.044 instead of 0.046
ye ik lmao i think whoever made these solutions basically was just speedrunning tf outta the exam but yeah it should be 0.046

Part (a) was finding Ka of dichloroacetic acid and part (b) was using gibbs energy and Ka values to explain the difference in strength of the acids

for the sols Q28 using bromine water doesnt CONFIRM that the compound is an alkene as alkynes also decolourise right? Wouldn't further testing be required to really CONFIRM its an alkene?
