i inputed: -Log(5.20 x 10-4) ph=3.28 but its incorrect?
okay, i got 2.8E-4 mols of NaOH and 8e-4 MOLS of acetic acid, so do i just plug in mols of hcl into -log(hcl)?
need the check pls
thats not the ansr, need a check
on this one i got:2,16,2,2,8,4 but it say that the second(2)which is the coefficent for C204(2-) and the 4 on the co2 is wrong ? what might be the problem?
i got 1,8,1,1,4,1 but the second coeffient(one) and the last coeffient(one) are incorrect. im not sure what goes for ____Fe(2+) and ___Fe(3+)
i see what my problem is, thanks i got it.
iam confused with the ice table could you show me because my answer .0002 is incorrect thanks.
thanks but i figured how to do this
