Question

Suppose that the NaOH sitting on the shelf had absorbed 1 g of water for every 1 g of NaOH. How would this have affected your results? A. The molarity of the NaOH solution would have been double what you expected. B. The molarity of the NaOH solution would have been half what you expected. C. It would not have affected the concentration of the NaOH solution nor the results of the titrations. D. The concentration of the NaOH solution would have been different, but the titration results would have been the same.

Explanation / Answer

Ans;- We know NaOH is highly hygroscopic so it can absorb water very easily,Therefore upon adding 1g of water for every 1g of NaOH, the molarity will become half than what we expected because due to hygroscopic nature of NaOH , there will a decrease in the concentration of NaOH resulting in less molarity.

Therefore the correct option is B)
