Question

calculate the ph of a mixture containing 50ml 0.1m

Answer 1

molarity=number of moles/volume in lit

here first find number of moles..that is

      0.1=n/0.05

      n=0.005

now we know number of moles ...then we know that

 n=c/v find 'c'

0.005=c/0.05

c=0.00025=concentration of h+ ions

then pH=-log[H+]

 pH=-log[0.00025]

      =3.6.
