2. B. And check a if possible 2. One reason a standard solution of NaOH cannot be prepared from solid NaOH is that solid NaOH ishygroscopic: it absorbs water vapor from the atmosphere. Assuming you calculated the concentration ofa NaOH solution by measuring the mass of a solid sample of NaOH and dissolving it in water, howwould this property of NaOH affect (e.g. increase, decrease, no change) the following steps in a titration?Justify your choice.The concentration of a NaOH solution made from solid NaOH that absorbed a significant amount ofwater prior to measuring its mass.Since the NaOH would absorb water, it's mass would be higher thanthat of just NaOH. When we do our calculation for concentration,our larger than actual mass will make the solution be calculatedmore concentrated than it really is.DSb. The volume of the resulting prepared NaOH solution needed to titrate an acid.a.

A titrant is the solution which is added from burette while a sample is taken in titration flask. It is sodium hydroxide here.A) since Sodium Hydroxide is hygroscopic in nature, so it absorbs moisture. When we do calculations using observed mass, we consider this mass and the calculated molarity will be higher than it actually is.B) Since actually concentration of sodium hydroxide is less, so more quantity of sodium hydroxide will be used to titrate an acid.NaOH + HA ----> NaA + H2OIncreaseIncrease
