How can you test if powder is talc or cornstarch?
One way to test if a powder is talc or cornstarch is by performing a iodine test. Mix the powder with iodine solution; if the mixture turns blue-black, it is likely cornstarch. Another way is to do a simple solubility test: dissolve the powder in water and if it is talc, it will not dissolve and settle to the bottom, while cornstarch will dissolve.
How can a half test tube of sugar and a half test tube of water add up to one full test tube?
When sugar dissolves in water, it occupies space within the water molecules, leading to an increase in volume. So, if you dissolve a half test tube of sugar into a half test tube of water, the volume of the mixture will be greater than the sum of the individual volumes of sugar and water, resulting in a full test tube.
What is the dependent variable in an experiment to test how fast sugar dissolves in hot water?
The dependent variable in this experiment would be the time it takes for the sugar to completely dissolve in hot water.
How do you conduct the solubility test?
To conduct a solubility test, add a small amount of the substance to a test tube of solvent (such as water) and observe whether it dissolves. If it dissolves, the substance is soluble; if it does not dissolve, the substance is insoluble in that solvent. Repeat the test with different solvents to determine the solubility characteristics of the substance.
Why are lipids soaked in ethanol in an emulsion test?
Lipids are soaked in water because they do not dissolve in water but the ethanol will allow the lipid to dissolve such that when diluted the ethanol will fall out of solution to form an emulsion.
How could you test that instant coffee granules dissolve in water?
You could always put the granules in water....
Can you test pills in vinegar to see if they dissolve?
I thought that you could test pills in vinegar to see if they dissolve. That would tell you if they dissolve in your body.
How does a skittle dissolve in water?
well it depends on the tempeture...but for hot water it takes like maybe 34-40 minutes to dissolve in water and for cold water.. would maybeee 45-55 minutes to dissolve..but you guys should test it just to make sure ;)
What scientific test distinguished marble from chalk?
The "Izite Test" named after the german scientist "Gude Izite" allows one to tell the difference between marble and chalk.

How do detergents and soaps work?
the "soap or detergent" act like solvents which dissolve into the water creating the water to be a cleaning solution (this was on my science test and this is the scientific term)

How can you tell if its an acid?
Add an alkali substance to it, such as chalk, if it is an acid it will "fizz" and release carbon dioxide. You could also test with Litmus Paper or Universal indicator.
What substances will dissolve easly in water?
The two basic substances that dissolve easily in water are sugar and salt. It's a little harder to have flour dissolve in water, though. This is a great opportunity for you to test things out! Get a small glass of water. Grab a pinch of a powdery substance such as cinnamon or nutmeg. Drop the powdery substance into the glass of water, and watch it carefully for about 6 or 10 minutes.
How do you test different solvents to test different solids to see if they are soluble?
A very good way to see if some solid is soluble in a solvent is to see if the solid has the same polarity. If these oppose they will not!! dissolve or even mix. Most Salts are soluble in a polar solution like Water. There are other solids that need something like petrol or an organic Solvent to dissolve them. You could also search for the "Solubility Rules".
What is the dependent variable in an experiment to test how fast sugar dissolves in hot water?
The dependent variable in this experiment would be the time it takes for the sugar to completely dissolve in hot water.
What color should the flame test carried out on a sample of chalk give?
red :)
