What volume of ethanol 96 percent should be added to 500 ml of 70 percent ethanol such that when the mix is made to 2.5l with water the final conc of ethanol is 55 percent?
First calculate how much ethanol you need in the final solution. 55% X 2.5l = 1.375l Then calculate how much ethanol you already have in the solution. 0.5l X 70% = 0.35l Now take the difference between those two numbers as the extra amount needed. 1.375l - 0.35l = 1.025l Now correct for the fact that you are adding only 96% ethanol. 1.025l / 96% = 1.068l Answer: 1.068l
What percent of gasoline consists ethanol that is made from corm?
In the United States, gasoline typically contains up to 10% ethanol, which is mostly made from corn. This ethanol, known as E10, is added to gasoline to reduce emissions and dependence on fossil fuels.
Does the pH of ethanol change if water is added?
Yes, adding water to ethanol will change its pH. Ethanol is a neutral compound with a pH of around 7. However, adding water will dilute the ethanol, potentially changing its pH depending on the amount of water added and the initial concentration of the ethanol solution.
Does the colour of potassium permanganate persist when it is added initialy to heated 3ml of ethanol?
When potassium permagnate is added initially to ethanol, ethanol gets oxidised into ethanoic acid using potassium permagnate. Thus, decolorizing potassium permagnate. When excess is added , the color of potassium permagnate persists.
What must be added to an aqueous solution of glucose to convert it into ethanol?
Yeast is added to the aqueous solution of glucose to convert it into ethanol through fermentation. Yeast enzymes break down glucose into ethanol and carbon dioxide.
How many gallons of gasoline that is eight percent ethanol must be added to two thousand gallons of gas with no ethanol to get a mix that is four percent ethanol?
400 gallons of gasoline with 8% ethanol must be added to the 2000 gallons of gas with no ethanol to achieve a mixture that is 4% ethanol. This is because in the final mixture, the quantity of ethanol is the average of the ethanol content in the two types of gasoline.
What are the chemical steps for converting corn to ethanol?
Corn is first ground into a fine powder, which is then mixed with water and enzymes to break down the starch into smaller molecules. Yeast is then added to ferment the sugar into ethanol, carbon dioxide, and heat. The mixture is distilled to separate the ethanol from the other components, resulting in pure ethanol.

How much water should be added to 30 gallons of a solution that is 70 percent antifreeze in order to get a mixture that is 60 percent antifreeze?
First off do not use tap water. Use only distilled water. You will need to add 3 gallons of distilled water to the solution to get 60% antifreeze and 40% distilled water or a 60/40 mix.
Why do you think ethanol is used in saponification process?
Ethanol is added to hasten saponification.
Why methanol is added to ethanol?
To avoid misuse of ethanol for drinking purpose it is denatured with methanol.
Do Flying J stations add ethanol to their gasoline?
No, it comes in with the ethanol already added.
What are the solvent and solute in a containing 100g of ethanol and 3g of sucrose?
solvent=ethanol solute=sucrose because sucrose is added to ethanol.
