when 10g. of sodium chloride is added in 100ml. of water , how does it affect the vapour pressure of water ? plz .. quick ans. i am waiting .... |

Answer» Vapour pressure will decreaseExplanation:BOILING point is TEMPERATURE at which the vapour pressure gets equal to atmospheric pressure. Now when we ADD Nacl or salt to water, the salt being non volatile would TAKE some area of water and would DECREASE the vapour pressure of water. This would mean that the boiling point of the solution would be achieved earlier when compared to pure water. |
