Asked by Franky
2 quick questions:
I am stuck on this:
1) The concentration of hydrogen ions in a 0.1 mol dm3 solution of phosphoric acid, H3PO4?
I would be able to do it if I knew the correct equation that = H3PO4 but I can't work it out.
2) In titrations why would more than three significant figures not be appropriate for the final answer?

I worked 1) for you below. Look at your previous posts before posting a duplicate.
2) You are limited to 3 s.f. because of the 0.100. There are three in that. The other values are to four s.f. but you are allowed the least in a series of numbers.

Ahh ok, sorry I had been looking a lot, I just didn't see it so I thought I'd post it again.
Thank you!
