alcohol and water mixture

Vapor

Consider a binary mixture of ethanol and water Vapor-liquid equilibrium (VLE) data can be computed using the modified Raoult's law: where is the vapor pressure is the total pressure and are the liquid and vapor phase mole fractions of the light component (i e ethanol) when and finally is the activity coefficient You can vary the pressure to any value between and (i e low to

will water mixed with rubbing alcohol freeze? : askscience

I read online that if you do a 50/50 mix of water and rubbing alcohol then spray it on a windshield that's frosted over there's a chemical reaction that almost instantly defrosts your windshield but if i leave that mixture in my car will it freeze solid? or will the rubbing alcohol keep it from freezing?

Alcohol and Water Safety

Alcohol and water don't mix Alcohol contributes to at least 20 per cent of all adult drowning deaths every year This rises to 41 per cent in the 15–29 years age group but the overall figure is likely to be higher as alcohol is not tested for in all drowning deaths
