What is the effect on the boiling point of a solution (for example, water) produced by a soluble nonvolatile substance (for example, sodium chloride)? What is the effect of an insoluble substance such as sand or charcoal?
I believe if an insoluble substance is added, then the boiling point will remain the same because it does not affect the solution due to it not mixing and producing a new solution.
As for a soluble substance being added, I would think the boiling point would change since it would produce a new product or solution. Would it go up or down? i'm not sure
Any help would be appreciated, thanks!

adding a soluble substance raises the bp, and lowers the fp.
soluble and non-volatile impurity would have two effects on liquid whose boiling point is to be dteremined.
1.it affects the forces between the molecules.
2.it decreases the vapour pressure .thereby increases the boiling point if atm is high or decreases the boiling point if atm is low
