Answer : The mass of sulfuric acid needed is .
Solution : Given,
pH = 8.94
Volume of solution = 380 ml =
Molar mass of sulfuric acid = 98.079 g/mole
As we know,
Now we have to calculate the moles of .
Formula used :
For neutralization, equal number of moles of ions will neutralize same number of
ions.
As,
From this reaction, we conclude that
2 moles of ion is given by the 1 mole of
moles of
ion is given by
moles of
Now we have to calculate the mass of sulfuric acid.
Mass of sulfuric acid = Moles of × Molar mass of sulfuric acid
Mass of sulfuric acid =
Therefore, the mass of sulfuric acid needed is .
