anonymous · Answer

let me ask you a question, what happens to a boiling point of solvent when solute is added?

anonymous · Answer

I dont know lol. Im clueless

anonymous · Answer

Chemistry isnt a easy thing for me

anonymous · Answer

ok so when you add solute in solvent, solvents boiling point ie boiling temperature rizes, now that we know that lets find out what is boiling point... 
so do you know what is boiling point?

anonymous · Answer

No lol

anonymous · Answer

Isnt it when it reaches a certain tempertature or no?

anonymous · Answer

boiling point is a temperature at which vapor pressure is equal to outside pressure
ok now that we know that temperature rizes with addition of solute in solvent what happens to vapour pressure in same case?

Ughhhh im so confused
