Why you dissolve absolute ethanol in 5 percent alpha naphthol for the Molisch test?
There is an answer in 'Related links', clickable just below this answer page [cf. Molisch's test for carbohydrates).
But there is no conformation to use absolute alcohol (100%), neither of 5% a-naphtol.
They use normal 96% alcohol and a-naphtol 2 g per 20 mL (=10%).
The site is in German language, but you'll find an 'English language' link below the 'disclaimer'.
What else can I help you with?
What is the composition of the molisch's reagent?
5% alpha-napthol in absolute ethanol
Will ethanol dissolve polypropylene?
Polypropylene is not dissolved in ethanol.
What happens when naphthalene and phenolphthalein dissolve in ethanol?
When naphthalene and phenolphthalein dissolve in ethanol it creates a crystal-like powder. The powder will also appear to have a yellow tinge and has no smell.
Why does water dissolve more salt than ethanol?
Water is polar, and so is salt (because it's ionic and therefore polar by definition.) So salt dissolves easily in water, because in chemistry, "like dissolves like." Ethanol is non-polar (because it's a hydrocarbon, and they're all non-polar.) So water and ethanol won't dissolve in each other. Nor will ethanol dissolve salt.
What temperature does iodine dissolve in alcohol?
Iodine is dissolved in ethanol at any temperature.
Is 2-naphthol soluble in ethanol?
yes, it is much more soluble in ethanol than in water.
What is the composition of the molisch's reagent?
5% alpha-napthol in absolute ethanol
What is the composition of molisch test?
molisch reagent is prepared by dissolving 5g of alpha napthol in 100 ml alcohol
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.
Does potassium chloride dissolve in ethanol?
Yes, potassium chloride is soluble in ethanol. When added to ethanol, potassium chloride will dissolve to form a clear solution.
Does sand dissolve in Ethanol?
No, sand does not dissolve in ethanol. Sand is mainly composed of silicon dioxide, which is insoluble in ethanol.
Will ethanol dissolve polypropylene?
Polypropylene is not dissolved in ethanol.
Does beeswax dissolve in ethanol?
Yes, beeswax does dissolve in ethanol. This can be useful for creating natural products such as creams or ointments where beeswax serves as a thickening agent.
Can ethanol dissolve in alcohol?
Yes, ethanol is a type of alcohol and it can dissolve in other alcohols. Ethanol is commonly used as a solvent in many industries for this reason.
Does glass powder dissolve in ethanol?
Glass powder does not dissolve in ethanol. Glass is composed mostly of silicon dioxide, which is insoluble in most solvents, including ethanol.
How does baking soda dissolve in ethanol?
Baking soda (sodium bicarbonate) does not dissolve in ethanol. Baking soda is only soluble in water and not in organic solvents like ethanol.
Will butter dissolve in ethanol?
No, butter is not soluble in ethanol. The nonpolar nature of butter and the polar nature of ethanol make them immiscible. Butter will not dissolve in ethanol, but instead will float on top or form a separate layer.
