Why is ethanol a better solvent than water for recrystalization?
Ethanol has a lower polarity compared to water, making it a better solvent for organic compounds that are less soluble in water. This allows for better selective solubility during recrystallization, resulting in purer crystals being formed. Additionally, ethanol has a higher boiling point than water, which can help in achieving complete dissolution of the compound at higher temperatures.
Why would ethanol be better than plain water for removing a grease stain?
Ethanol is a solvent that can dissolve grease stains more effectively than plain water due to its chemical properties. Ethanol has a better ability to break down the grease molecules and lift them from the surface, making it more efficient for stain removal.
Which has a greater volume 1000g of water or 1000g of denatured ethanol?
1000g of water has a greater volume than 1000g of denatured ethanol because water is denser than ethanol. This means that water occupies less space per gram compared to ethanol.
Why the ice will float in 5 kg ethanol than the 1 kg water?
Ice will float in ethanol because ethanol has a lower density compared to water. When ice is placed in ethanol, the difference in density causes the ice to be less dense, and therefore float. This is different from water, where the ice is denser than the liquid water and sinks.
Does ethanol float or sink in water?
Ethanol floats on top of water because it is less dense than water. Ethanol and water do not mix well due to differences in polarity and intermolecular forces.
Why ethanol not suitable in Gas chromatography?
Its alcohol so it can purify the chemicals used in the experiment. Furthermore, it will travel up the filter paper better than water will. Ethanol is pure whereas water may have other things in it such as chlorine is in tap water
Why would ethanol work but not with water when using felt tip pens in an chromatography experiment?
Ethanol would work because it is alcohol-induced, therefore, it is stronger than water.
Why is water a better conductor than ethanol?
Water is a better conductor than ethanol because it contains ions that can move freely and carry electrical charges, while ethanol does not dissociate into ions as readily. This means that water can facilitate the flow of electricity more easily than ethanol.
Which is a better solvent for boiling point elevation ethanol or water?
Ethanol is a better solvent for boiling point elevation compared to water. This is because ethanol has a higher boiling point than water. When a solute is added to ethanol, it will raise the boiling point of the solution more significantly than if the same solute were added to water.
Why is ethanol a better solvent than water for recrystalization?
Ethanol has a lower polarity compared to water, making it a better solvent for organic compounds that are less soluble in water. This allows for better selective solubility during recrystallization, resulting in purer crystals being formed. Additionally, ethanol has a higher boiling point than water, which can help in achieving complete dissolution of the compound at higher temperatures.
Is biofuel better then ethanol?
Ethanol is one of the biofuels, so it can't be better than itself.
Why would ethanol be better than plain water for removing a grease stain?
Ethanol is a solvent that can dissolve grease stains more effectively than plain water due to its chemical properties. Ethanol has a better ability to break down the grease molecules and lift them from the surface, making it more efficient for stain removal.
Which liquid expands more Ethanol or Water?
Ethanol expands more than water when heated because it has a higher coefficient of thermal expansion. This means that ethanol will increase in volume more than water when heated to the same temperature.
Which fluid will float 5 kg of ethanol or 1kg of water?
1 kg of water will float in ethanol because ethanol is less dense than water.
Which has a greater volume 1000g of water or 1000g of denatured ethanol?
1000g of water has a greater volume than 1000g of denatured ethanol because water is denser than ethanol. This means that water occupies less space per gram compared to ethanol.
Why does ethanol burn differently than ethanol and water mixed?
Ethanol burns differently than a mix of ethanol and water because water has a higher boiling point compared to ethanol. Water will absorb heat during combustion, which can lower the overall temperature and affect the efficiency of the burning process. This can lead to a slower and less complete combustion compared to pure ethanol.
Would ethanol be better than mercury for an outdoor thermometer in the arctic?
Ethanol would be better than mercury for an outdoor thermometer in the Arctic because ethanol has a lower freezing point than mercury, making it more reliable in extremely cold temperatures. Additionally, ethanol is less toxic than mercury, which is important for environmental and safety reasons in outdoor settings.
