why? well.. first of all u must comlete the mixtur blah blah blah go to collage !
For each 100 ml that you want, add 90/.96 ml, which is 93.75 ml, of 96% ethanol, then make up the difference to 100 ml with water.
The liquid that boils at a lower temperature will become a gas first and this will be the first one that you collect. Water boils at 100 degrees C and methanol boils at 64.7 degrees C so you will collect methanol first and then water.
The mixture water-ethanol is homogeneous.
Ethanol is not a mixture at all. It is a compound and therefore a pure substance.
Coz, methanol reduces the freezing point of the mixture to under -30o C
Methanol is made by a method different from that used in the preparation of ethanol. The naphtha fraction from the distillation of crude petroleum, is used as a raw material for the manufacture of methanol. When naphtha is reacted with a high steam ratio, under pressure and at a high temperature, synthesis gas of low methane content is obtained. Most of the carbon from the naphtha is converted to carbon monoxide and carbon dioxide which can be removed from the gaseous mixture to leave a high purity of hydrogen. When a mixture of hydrogen and carbon monoxide in the ratio 2:1 is passed over a catalyst (e.g. a mixture of zinc oxide and chromium oxide) under high pressure and at a high temperature, methanol is formed.
Methanol has a Boiling point under standard conditions of 64.7 °C, and ethanol of 78.4 °C. You I can boil off vapor and collect Methanol and Ethanol, and use that cooled back down to liquid form and preform a test.
bastet
A heterogeneous mixture is a sum of pure substances which are not soluble in each other while a homogeneous mixture is a mixture wherein its constituents do not appear separately. Methanol is an example of a homogeneous mixture.
I dont think so because ethanol, containing an OH group is readily soluble in water.
The liquid that boils at a lower temperature will become a gas first and this will be the first one that you collect. Water boils at 100 degrees C and methanol boils at 64.7 degrees C so you will collect methanol first and then water.
Denatured alcohol.Methylated spirits is a mixture of roughly 95% methanol and 5% ethanol.
The mixture water-ethanol is homogeneous.
No. Ethanol is also alcohol. Ethanol is a compound. It is not a mixture.
Ethanol is not a mixture at all. It is a compound and therefore a pure substance.
Methanol is an alcohol and consists of carbon,hydrogen and oxygen its formula is CH3OH
Ethanol is a pure substance, but it is rare to encounter it pure. Laboratory alcohol usually contains small amounts of water and methanol. Alcoholic drinks contain large quantities of water, as well as flavourings.
Pure ethanol, CH3CH2OH, is an pure organic compound and not a mixture
