pH indicators need to accommodate proton transfers and provide a distinguishable colour change. I put down it would work primarily for weak acids as their equivalence point is somewhere in the 3-7 range. Any thoughts on this?
An 88 last year aligned to 95 I think last year. In my opinion the cut off will increase this year so, you're probably looking at around 95-96. But saying that I think the markers will not give marks out easily this year
