the first footnote seems wrong to me!

the "actual" (actual what?) mass ratio of the concentrate acid mixture is not less 2:1

you have:

35% HCl 1,18g/ml 11Mol/l

65% HNO3 1,4g/ml 14Mol/l

you need:

3Mol = 270ml ~ 318g

1Mol = 70ml ~ 98g

that a bit more than 3:1

or - if it means that a 3:1 volume based mixture is it:

300ml HCl = 354mg

100ml HNO3 = 140mg

I don't see the (less than) 1:2 ratio on what is this calulated?

in the case I am wrong - it should be said in a way that other could understand what you mean. --Struppi (talk) 06:30, 3 November 2015 (UTC)[reply]
