A solution is saturated with dissolved minerals - what will happen if 50 percent of the water in the solution evaporated?
When 50 percent of the water evaporates from a saturated solution, the concentration of the dissolved minerals will increase as the same amount of minerals now remains in a smaller volume of water. This may lead to the precipitation of some minerals, resulting in the formation of solid crystals at the bottom of the container.
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.
What is the difference between a percent saturated solution of ammonium sulfate and percent wv solution of ammonium sulfate?
Bioc 4025? Just a guess. Definition of % Saturation: The amount of a substance that is dissolved in a solution compared to the amount that could be dissolved in it. % w/v Solution: This is in terms of weight (g) per volume (mL). 2% for example is 2 g per 100 mL. gl
How do you prepare 95 percent ethanol from absolute ethanol?
To prepare 95% ethanol from absolute ethanol, you would need to dilute the absolute ethanol with a calculated amount of distilled water. Since absolute ethanol is 100% pure, you can use the formula C1V1 = C2V2, where C1 is the initial concentration (100%), V1 is the volume of absolute ethanol, C2 is the desired concentration (95%), and V2 is the final volume of the diluted solution. By rearranging the formula and solving for V1, you can determine the volume of absolute ethanol needed to achieve a 95% ethanol solution when mixed with water.
Is it possible to have an absolute alcohol from ninety percent ethanol using fractional distillation?
No, it is not possible to achieve absolute alcohol (100% ethanol) through fractional distillation of a 90% ethanol solution. Fractional distillation can only separate the components present in the solution, not create new ones. To obtain absolute alcohol, additional methods such as azeotropic distillation or molecular sieves are needed.
A solution is 10 percent ethanol if you have 6L of solution how much ethanol is is the solution?
10% of 6L is 600 ml. 6000 / 100 * 10 = 600 ml.
How would I answer this question How many grams to 0.1 g of ethanol should be dissolved into 135 g of water to produce a 23 percent by mass ethanol solution?
The answer is 31,05 g ethanol.
What is the percent volume of ethanol?
The percent volume of ethanol in a solution is the volume of ethanol divided by the total volume of the solution, multiplied by 100. It is commonly used to express the concentration of ethanol in alcoholic beverages or solutions.
What has a percent by volume of 0.038?
A solution with a percent by volume of 0.038 contains 0.038 liters of solute dissolved in 100 liters of solution. This means that 0.038% of the total volume is the solute.
10ml of ethanol mix with 40ml of water find percent concentration of ethanol solution?
The total volume of the solution is 10ml + 40ml = 50ml. The percentage concentration of ethanol in the solution is (10ml / 50ml) * 100% = 20%.
What is the mass of ethanol dissolved in one liter of a 6.8 percent ethanol solution?
1 liter exactly equals 1000 cubic centimeters (abbreviated cc, or cm3). A 6.8 percent solution means that of those 1000 cc's, 68cc's are of ethanol ((6.8/100) x 1000) Assuming pure ethanol, which it most likely is for a school problem, Wikipedia states that the density is: 0.789g/cm3 (0.789g/cc) so, 68 x 0.789 = 53.652 grams.

100-proof alcoholic beverage contains percent ethanol?
50% alcohol.
What is the percent by volume of 45 mL of ethanol dissolved in 125 of water?
To calculate the percent by volume, add the volumes of ethanol and water together (45 mL + 125 mL = 170 mL). Then determine the percentage of ethanol in the total volume by dividing the volume of ethanol by the total volume and multiplying by 100 (45 mL / 170 mL * 100 ≈ 26.47%). Therefore, 45 mL of ethanol dissolved in 125 mL of water represents approximately a 26.47% ethanol solution by volume.
Does nadh can be dissolved by 75 percent ethanol?
I've never tried it...but I would bet the answer is yes as they are both organic compounds.
What are the components of a 5 percent Sodium Chloride solution?
This solution contain 5 g NaCl dissolved in water.

This may lead to the precipitation of some minerals, resulting in the formation of solid crystals at the bottom of the container.
What is 7 percent Tincture of iodine?
7 percent Tincture of iodine is a solution that contains 7 parts of iodine and 93 parts of alcohol, usually ethanol. It is commonly used as an antiseptic to cleanse and disinfect wounds or before surgical procedures.
