Question

HELP! Calculate the p value of each ion indicated:
Ba2+, Mn2+, Cl- in a solution of BaCl2 7.65x10-3 M and MnCl2 1.54 M

Answer 1

whats p vale..?

Answer 2

I think is like the pH, but for every ion, pBa, pK, pCl...

Answer 3

listen u just find normality after finding equivalent wieght of Ba+2,Mn+2,Cl- then put in the formula
concnt of ion/concn of salt ok
do ths much

Answer 4

nw just put values
pH=pKa + log concn of ion/concn of salt
and then u ll get ans :) but yes in Ba case u ll get pOH dont forgot to subtract it by 14 as pH+ pOH=14

Answer 5

equivalent weight /molecular weight=normality ok

Answer 6

vicky u cal. normality

Answer 7

27/208=normality
12 x10^-2 approx=normality
nw Ka=14.3 x 10^-3
pKa=log 14.3 x10^-3
pKa=3-log14

Answer 8

now after gettin pKa put it in the formula
pH=pKa + log concn of ion/concn of salt
u ll get it ok
