check this anand
sir hiw to calculate kw here
kw is ionic product constant of water... H+ =Oh- so if H+=10^-7 then kw=10^-14
im not getting it,
ok wait
.
kw is ionic product constant of water i.e kw=[H+][OH-]
for 1st i accept it but in second case, they given 10^-12
10^-8 should be na
how anand?
h+ and oh - =10^-14 then
im i right?
Anand here it is given na pure water so concentration of H+ equal to concentration of Oh-.. and kw=H+ Oh-.. so 10^-6 ×10^-6=10^-12
now got anand?
ok
