what would the concentration of the solution of a sulfuric acid be titration of a 25.0 ml sample of acid required 20.00 ml of a 0.20 naoh standardized solution for it to become neutralized

1 answer

2NaOH + H2SO4 ==> Na2SO4 + 2H2O
mols NaOH = M x L = ?
Look at the coefficients in the balanced equation. 1 mol H2SO4 = 2 mols NaOH; therefore, mols NaOH/2 = mols H2SO4.
Then M H2SO4 = mols H2SO4/L H2SO4. You know mols and L, solve for M.
