What is an Anthrone test?

The Anthrone test is a chemical test used to detect the presence of carbohydrates, specifically monosaccharides and disaccharides, in a sample. It involves adding Anthrone reagent to a sample, which produces a blue color in the presence of carbohydrates. The intensity of the blue color can be used to estimate the concentration of carbohydrates in the sample.


If a liquid sample of naphthalene is heated and remains at 218C until it is completely vaporized you know that 218C is the of naphthalene.?

The temperature of 218°C at which the liquid sample of naphthalene remains constant during vaporization indicates its boiling point. At this temperature, the vapor pressure of naphthalene equals the atmospheric pressure, allowing it to transition from a liquid to a gas. Therefore, 218°C is the boiling point of naphthalene under the given conditions.


How do you mask the color given off in a flame test with the normal color of fire?

If you open the valve on the bunsen burner fully the flame becomes virtually invisible and therefore there are no interactions between the original flame colour and the colour produced by the chemical.


What substance is given off when the salt solution is heated gently?

Water vapor is given off when a salt solution is heated gently. As the solution heats up, the water molecules begin to evaporate, leaving behind the salt particles.


What happens when barium chloride is heated?

When heated gently, the red burgundy CoCl2.6H2O will decomposes into the violet CoCl2.2H2O then to the blue anhydrous CoCl2. Note: When this anhydrous compound is dissolved in water it will go back to the original red burgundy color.

How to find the percent by mass of a compound in a given sample?

To find the percent by mass of a compound in a given sample, you need to divide the mass of the compound by the total mass of the sample and then multiply by 100. This will give you the percentage of the compound in the sample.
