Question

Which property of an unsaturated solution of sodium chloride in water remains the same when more water is added to the solution?

Answer 1

Choice 3) The absolute mass of the sodium chloride itself will not change since only water is added but there will be a higher ratio of water to sodium chloride so any ratio-based property will change. Boiling point is including as being directly affected by the ratio of water to sodium chloride so this would also change when more water is added.
