<span>The water cycle has no starting point. But, we'll begin in the oceans, since that is where most of Earth's water exists</span>
27/208 = normality
12 x 10^-2 approx = normality
nw Ka = 14.3 x 10^-3
pKa = 3 - log 14
now, after getting the pKa put it in formula :
pH = pKa + log concn of ion/concn of salt and you'll get it
hope this helps
