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.
What happens when ethanol is added to soap?
From the experiment, why is a mixture of ethanol and water instead of simply water itself used for saponification? ... Ethanol is the catalyst in saponification C. Ethanol would help the soaps obtained from saponification reaction become more soluble in water D.
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.
How many grams of sucrose must be added to 500 g of water at 100 celsius to change the vapor pressure to 755 mm Hg?
To change the vapor pressure of water to 755 mm Hg at 100°C, you would need to add sucrose to create a solution with a lower vapor pressure than pure water. The amount of sucrose needed to achieve this specific vapor pressure depends on the molal concentration of the sucrose solution and its van't Hoff factor. To calculate this accurately, you would need additional information about the sucrose-water system.
How do you prepare 1M ethanol?
You take 1 mol = 46 gram of pure alcohol (or equivalent 46 * [100 / masspercentage] of diluted) and add it up with water while stirring to make it 1 Litre.[Roughly you'd have to take 60 mL 96% ethanol (this is commercially available, don't use denaturated spirit!) and fill up to 1 L.]
How do you prepare a thirty percent sucrose solution?
To prepare a 30% sucrose solution, dissolve 30g of sucrose in enough water to make a total of 100mL solution. Measure out the correct amount of sucrose using a balance, then add water and stir until the sucrose is completely dissolved.
How many distilled water will be added to prepare 1000 ml 95 percent ethanol from 1000 ml 99 percent ethanol?
1. Extract 959,6 mL from the 99 % solution. 2. Add 40,4 mL water.
When is water a solute?
We normally think of a solute as a solid that is added to a solvent (e.g., adding table salt to water), but the solute could just as easily exist in another phase. For example, if we add a small amount of ethanol to water, then the ethanol is the solute and the water is the solvent. If we add a smaller amount of water to a larger amount of ethanol, then the water could be the solute!
Describe an experiment used to find out whether there is any temperature change on mixing ethanol and water?
Measure equal amounts of water and ethanol in separate containers. Take temperature of both. Add ethanol to water and take temperature.
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.
How does one prepare 95 percent of ethanol from 100 percent?
Find the volume of the 100% ethanol Add 1/19 of water to the volume (if it is like 190ml, add 10ml of water since 190/200=95%)
What can D5 0.9 NaCl do to a patient?
The solution is used to add water, sucrose and sodium to the organism.
How could you obtain sugar crystals from the sugar solution without losing the ethanol?
By heating ethanol is evaporated and sugar remain as a solids.
What to do to make ethanol as water immiscible?
To make ethanol immiscible in water, you can add a substance that forms a separate layer, such as a nonpolar solvent like hexane or diethyl ether. This will create two distinct layers where ethanol is separated from water. Using a separation funnel, you can then extract the ethanol layer from the water layer.
What happens when ethanol is added to soap?
From the experiment, why is a mixture of ethanol and water instead of simply water itself used for saponification? ... Ethanol is the catalyst in saponification C. Ethanol would help the soaps obtained from saponification reaction become more soluble in water D.
How you would make 400 ml of a 50 percent Sucrose water solution?
To make 400 ml of a 50% sucrose solution, you would mix 200 ml of sucrose with 200 ml of water. Measure out 200 ml of sucrose and dissolve it in 200 ml of water, ensuring the sucrose is completely dissolved to create the 50% solution.
