It was found that 25 ml of a sodium hydroxide solution, which per liter contains 4 g of commercial caustic soda, is equivalent to 12 ml of 0.2 N sulfuric acid. Calculate the percentage of impurities in commercial caustic soda. Note that the molecular weight of NaOH is equal to 40 g/mole. * 4.91 % O 4.5 % O 3.7% O 5.3 % 4.0 %
