A solution containing 1.20 g of impure sodium hydroxide solution per Liter. In a titration, it requires 18.5 L of 0.500 mol/ L of sulfuric acid to neutralize 20.0 L of the impure alkaline solution completely. The chemical reaction is shown below. 2NaOH + H2SO4 Na2SO4 + 2H2O

Determine the concentration of NaOH in mol/L

•what conclusions can you make about the relationship between the volume of a gas and its temperature? • what conclusions can you make about the relationship between the volume of a gas and its pressure? • what possible variables have you not accounted for? as you did the procedures, is it possible that the atmospheric pressure may have changed? if it did change over the course of your experiment, then how would your results have been affected?
