yes, u can test this by putting the chalk in water

∙ 14y agoPresumably, one could dissolve a certain amount of flour in water, then look for the bromate anion in the water. Bromate anion research methods are good to ppb levels.
Ammonia gas can be tested in these ways:1. It has a pungent smell2. It turns MOIST red litmus paper blue3. Test its alkalinity in water (pH ~ 11)4. It will extinguish a lighted splint5. It will easily dissolve in water
not sure how to test but you can do a number of things to purify it you could use water purification tablets or boil the water to kill bacteria hope this helps
The fire will be extinguished. The better test for identifying carbon dioxide is to bubble the gas into lime water. Limewater will go cloudy because of chalk/limestone precipitation.
Yes. That's a good science project.That's what I'm doing for the science fair.I'm going to dissolve different types of pills with cold water and time which ones take more or less.Then we're going to test it again-but this time with hot water.Then wer'e going to be able to tell what is the difference between using hot water and cold water.
You could always put the granules in water....
I thought that you could test pills in vinegar to see if they dissolve. That would tell you if they dissolve in your body.
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 ;)

The "Izite Test" named after the german scientist "Gude Izite" allows one to tell the difference between marble and chalk.
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.
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)
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.
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".
The procedure is for the sample to be suspended in ethanol, allowing lipids present to dissolve. The ethanolic solution is then decanted into water. Since lipids do not dissolve in water, when the ethanol is diluted, it falls out of solution to give an emulsion. b8d7e385-e2f2-47f5-8c06-26f0aee337b6 Y2:b8d7e385-e2f2-47f5-8c06-26f0aee337b6
