Question

Suppose you have 1.00 L of an aqueous 1.00 M NaCl solution. Does the NaCl concentration of the remaining solution decrease, stay the same, or increase with the following changes?

(Assume each change is done separately to the original solution.)

-Letting half of the water evaporate from the solution -Adding an additional 1.00 L of water to the solution -Pouring out half of the solution -Adding another 0.500 L of 1.00 M NaCl solution into the original solution -Dissolving an additional 25.0 grams of NaCl into the solution

Explanation / Answer

a) concentration of the remaining solution Increase

b) concentration of the remaining solution decrease

c) concentration of the remaining solution Stay the same

d) concentration of the remaining solution Increase

e) concentration of the remaining solution increase
