nechirwan · Answer

whats the relation between  pH with concentration of Hydrogen ion?
and relation  between pOH  with  concentration of  hydroxide ion ?

anonymous · Answer

I can't really recall the relation and the way to calculate it!

nechirwan · Answer

ok
pH = -log[H]
pOH= -log[OH]
pH+pOH=14 
can u solve it now ?

anonymous · Answer

here is what I did, -log(10)=-1
ph+-1=14
=15
???

nechirwan · Answer

lol its $$10^{-5}    $$ not 10

anonymous · Answer

:( I totally forgot the way...thanks Alot Nechirwan, the answer is 9 :)

nechirwan · Answer

yes :D ur welcome
