2. one reason a standard solution of naoh cannot be prepared from solid naoh is that solid naoh is
hygroscopic: it absorbs water vapor from the atmosphere. assuming you calculated the concentration of
a naoh solution by measuring the mass of a solid sample of naoh and dissolving it in water, how
would this property of naoh affect (e. g. increase, decrease, no change) the following steps in a titration?
justify your choice.
a. the concentration of a naoh solution made from solid naoh that absorbed a significant amount of
water prior to measuring its mass.
b. the volume of the resulting prepared naoh solution needed to titrate an acid.
