What else can I help you with?
Anhydrous crystals were left uncovered overnight?
Anhydrous crystals are likely to absorb moisture from the air, causing them to become hydrated. This can alter the crystalline structure and purity of the crystals. It is important to store anhydrous crystals in a dry environment to prevent moisture absorption.
What substance changes blue anhydrous copper sulphate crystals to white?
Water changes blue anhydrous copper sulphate crystals to white by creating hydrated copper sulphate, which is white in color.
Anhydrous alumnium cloride cannot be obtained by heating crystals of AlCl3.6H2O why?
This is because when crystals of AlCl3.6H2O are heated, they decompose into AlCl3 and water vapor, rather than forming anhydrous AlCl3. The water molecules are released as steam, leaving behind anhydrous aluminum chloride. The presence of water molecules in the crystal structure prevents the formation of anhydrous aluminum chloride by simple heating.
How does hydrated potassium alum visually compare to the anhydrous form?
Hydrated potassium alum appears as colorless or white crystals with a smooth or glassy texture, while the anhydrous form typically appears as a white powder. Hydrated potassium alum can also exhibit water droplets on its surface due to its water content, whereas the anhydrous form does not show this characteristic.
What do you observe when copper sulphate crystals are heated?
With sufficient heating, the blue colored hydrated copper sulfate crystals common at standard temperature and pressure will lose their water of hydration and lose their blue color. With further heating, the anhydrous crystals will melt.
What is anhydrous crystals?
A anhydrous crystal is one that has had all of the water molecules removed from it, usually by heating the hydrated crystal to a constant mass.
What will happen if heat crystals of CuSO4 pentahydrate in a test tube and note the water given off allow to cool and compare the color of anhydrous CuSO4 with original crystals?
Heating crystals of CuSO4 pentahydrate in a test tube will cause the water molecules trapped in the crystal lattice to evaporate, leaving behind anhydrous CuSO4 crystals. The color change observed will be from blue (for the hydrated form) to white (for the anhydrous form).

If you add anhydrous sulphate to water do you get a chemical reaction?
yes you do. this is because the anyhdrate was white (crystals) and after adding water, it turned blue

- What would happen to the anhydrous cupric sulfate if you added water to it?
Anhydrous cupric sulfate would form hydrated copper(II) sulfate when water is added to it. This process is exothermic and the anhydrous crystals would dissolve as the water molecules bond with the copper sulfate molecules to form a hydrated crystal structure.
Is water anhydrous?
no. Water is not Anhydrous. Anhydrous means little or no water at all.
Crystals of dye are placed in water?
When crystals of dye are placed in water, they will dissolve if the dye is soluble. The dye molecules will disperse in the water, creating a colored solution. If the dye is insoluble, the crystals will remain visible in the water.
What does the difference between the few crystals of anhydrous calcium chloride and a few crystals of Glauber's salt when are exposed to the atmosphere?
Calcium chloride easily absorb water, it is hygroscopic.
