- Clean with deionised water. Measure from miniscus curve. Add drop by drop when reaching endpoint. Not sure if i got 3/3 tho

i got 7.01x10^20 for one

thank God. I got that too. I was scared for my life as the unit mg was unfamiliar to me. Plus squeezing this long value in the answer box was a bit tight and made me doubt myself...

That looks fine. I put clean with the solution, only start adding drop by drop when reaching the endpoint and pour the solution in using a funnel. I have no idea why I said use a funnel.

I've seen a past paper question asking roughly the same thing and I put: clean with deionised water, fill the tip of the burette with the solution (there was an air gap) and pour less solution into the burette so the start point in on the scale (it was higher than 0)
