Does ethanol affect salivary amylase activity?
Yes it does. As the concentration of EtOH increases, the ability of amylase to degrade starch lessens. That is, the rate at which starch is decomposed is less in magnitude as the concentration of ethanol increases.
HOW DO I CALCULATE THE PERCENTAGE BY MASS OF ETHANOL IN A MIXTURE OF ETHANOL AND WATER?
Divide the mass of the ethanol by the sum of the mass of the ethanol + that of the water and multiply by 100. Mass ethanol/(Mass ethanol + mass H2O) (x100)
Why theoretical value of ethanol in distillation process is differ with experimental value?
While the distillation is going on ,at 94.6% ethanol-water mixture forms an azeotrope which hampers further distillation.So ethanol cannot be made 100% pure.But concentration of ethanol can be increased by breaking the azeotrope by addition of benzene in large amount.
What is the link between percentage by volume and units of alcohol?
An UK unit of alcohol has 10 mL (8 g) ethanol. Calculate the mass or the volume of ethanol in your drinks.
Is there a simple equation to calculate the concentration given the absorbance and a time?
You need a graphic concentration versus absorbance.
What happens to the freezing points as the ethanol concentration increased?
The answer depends on the substances in the mixture in which the ethanol concentration increases.
Ethanol freezing point concentration?
At -114.1°C Ethanol Melts from its frozen state
What do you do if you drink ethanol?
Ethanol is another name for alcohol. Depending on amount and concentration, you may get drunk.
10ml of ethanol mix with 40ml of water find percent concentration of ethanol solution?
20%
How many syllables in xanthophyll?
In xanthophyll there are 3.
What concentration of ethanol is the most effective bactericide?
70%
Why is water a better conductor than ethanol?
water contains iron and ethanol doesnt. this is why Water has ions, ( not iron), in a higher concentration than ethanol.
How pure is distilled alcohol?
Industrial distilled ethanol (not from fermentation) can be obtained at 99,999 %.Ethanol from fermentation has a concentration of max. 96 %.
Does ethanol affect salivary amylase activity?
Yes it does. As the concentration of EtOH increases, the ability of amylase to degrade starch lessens. That is, the rate at which starch is decomposed is less in magnitude as the concentration of ethanol increases.
Alcohol is this process affected by temperature?
Yes, temperature affect the concentration of alcohol. Alcohol is made up of ethanol, high temperature oxidised ethanol to ethanoic acid so the concentration of alcohol decrease.
Is concentrated Ethanol blue in color?
Ethanol can reach up to 99% purity, which means highest concentration. Pure Ethanol is colorless exactly like water! Any color in ethanol is because of bad distillation or additives!
What concentration of Ethyl alcohol is effective bactericide?
