Why alcohol is always heated in warm water bath?
A water bath is used for heating alcohol, as this keeps alcohol (flammable) away from open flames.
How many cubic feet in a gallon of ethanol?
1 cubic foot = 7.4805 gallons, so 1 gallon of ethanol is 0.134 cubic feet
Is strontium bromide soluble in ethanol?
Yes, strontium bromide is soluble in ethanol. Ethanol is a polar solvent, and strontium bromide is an ionic compound, so it dissolves easily in polar solvents like ethanol.
Is ethyl alchohol a pure substance or mixture?
It is a pure substance.Added:Chemically speaking alcohol is meant to be ethanol, which is a pure compound with formula CH3CH2OH, it definitely is not a mixture, except when 'dissolved' in water (most stable solution: 4% water + 96% ethanol. (This is what you get when buying a bottle pure ethanol)
Is isopropanol or ethanol bigger?
Ethanol has two carbons, isopropanol has three carbons. So iso-propanol is larger in size.
Why 70 percent percent ethanol used in labs?
70% is the most effective concentration to denature poteins so killing bacteria. At 95% the ethanol just evaporates and leaves the protein untouched. Below 70% does not denature proteins. It also makes the ethanol less flammable.
Is gas more flammable than ethanol?
Well Ethanol is in gas when you fill it up with your car so it is the same thing but is very flammable that is why you shouldn't talk on the phone while pumping gas. Very dangerous explosions.
Why do you use 70 percent alcohol and not 90 percent while microbial culture?
Ethanol creates pores in the cell membrane of the microbial cell by solubilizing the lipoproteins of the membrane. The activity of ethanol determines its concentration. If we 90 percent ethanol, the amount of ethanol molecules available to act upon the cell is more and it attacks the cell membrane from all sides. The dissolved lipoprotein forms a kind of layer around the cell, due to which the alcohol is unable to act further and cause damage to the cell. However, if we use 70 percent ethanol, the amount of ethanol molecules are few and it is not able to attack the cell from all sides. Thus, pores are created intermittently in the plasma membrane, the ethanol penetrates the cell and damages it completely. So, 70 percent ethanol is preferable to 90 percent when using microbial cultures.
What is the percent by volume of ethanol in a solution that contains 48 mL of ethanol dissolved in 144 mL of water?
The total volume of the solution is 48 mL + 144 mL = 192 mL. The percent by volume of ethanol is calculated as (volume of ethanol / total volume of solution) * 100%. Plugging in the values, we get (48 mL / 192 mL) * 100% = 25%. So, the solution contains 25% ethanol by volume.
What chemical in alcohol makes it so flammable?
The flammability of alcohol is due to its high volatility and low flash point. The main chemical responsible for this is ethanol, which is the most common type of alcohol found in alcoholic beverages. Ethanol vaporizes easily and ignites quickly when exposed to a flame or spark, making it highly flammable.
How do you make 90 percent ethanol from 100 percent ethanol?
Well, darling, you can't make 90% ethanol from 100% ethanol because, sweetie, 100% means it's already pure ethanol. You can dilute it with a calculated amount of water to get to 90%, but you ain't changing that 100% ethanol into something else. So, mix it up with water like a fancy cocktail and voilà, you've got yourself some 90% ethanol.

A water bath is used for heating alcohol, as this keeps alcohol (flammable) away from open flames.
Why 95 percent ethanol is used in laboratory?
95% ethanol is commonly used in laboratories because it is an effective solvent for a wide range of chemicals and biological substances. It also has antimicrobial properties, making it useful for disinfecting surfaces and equipment. Additionally, 95% ethanol is less prone to evaporation compared to absolute ethanol, providing a more stable solution for various applications.
What is the difference between ethanol and water?
Ethanol is a type of alcohol, while water is a neutral compound. Ethanol has a lower boiling point and is flammable, while water is not. Additionally, ethanol is commonly used as a solvent, fuel, and beverage, while water is essential for life and has various important functions in biological systems.
How many cubic feet in a gallon of ethanol?
1 cubic foot = 7.4805 gallons, so 1 gallon of ethanol is 0.134 cubic feet
How many ml of ethyl alcohol are present in 50 ml bottle of rubbing alcohol?
Usually zero ml because ethanol is not normally used in rubbing alcohol. However, there is a little Ethanol-based rubbing alcohol and rubbing alcohol is usually 70 percent, so multiply 50 ml x .7 to get your answer.
