: A large amount of heat is released when strong acids are mixed with water. Adding more acid releases more heat. If you add water to acid, you form an extremely concentrated solution of acid initially. So much heat is released that the solution may boil very violently, splashing concentrated acid out of the container! If you add acid to water, the solution that forms is very dilute and the small amount of heat released is not enough to vaporize and spatter it. So Always Add Acid to water, and never the reverse.

What is the equation for anhydrous copper sulfate and water?
Anhydrous copper sulfate is CuSO4, while water is H2O. When anhydrous copper sulfate reacts with water, it forms hydrated copper sulfate, which is CuSO4·5H2O.
What happens when anhydrous calcium chloride is exposure to air?
Anhydrous calcium chloride will absorb moisture from the air, forming a hydrated form of calcium chloride. This process is known as hygroscopicity. It will eventually dissolve in the absorbed water to form a solution.
What happens if Copper Sulphate penta-hydrate is heated?
When copper sulfate pentahydrate is heated, it undergoes a dehydration reaction where the water molecules are released, leaving behind anhydrous copper sulfate. This process is reversible, and when anhydrous copper sulfate is exposed to moisture, it will reabsorb water and form copper sulfate pentahydrate again.
How does hydrate differ from a anhydrous ionic compound?
A hydrate is an ionic compound that has water molecules attached to its crystal lattice, while an anhydrous ionic compound does not have water molecules attached. Hydrates can easily lose or gain water molecules depending on the conditions, while anhydrous compounds remain stable without water.
What is the difference between a hydrous compound and an anhydrous?
A hydrous compound contains water molecules in its crystal structure, while an anhydrous compound does not contain any water molecules. Hydrous compounds can lose water when heated, converting into an anhydrous form.
What happens when a hydrate heated?
When a hydrate is heated, the water, h20 is evaporated, leaving only the anhydrous salt. If you add water to a anhydrous salt, it will transition back into a hydrate.
Is water anhydrous?
no. Water is not Anhydrous. Anhydrous means little or no water at all.
What is anhydrous or anhydrous?
anhydrous means if a substance contains NO water it is anhydrous. but if it is hydrated it contains water.
How do you prepare copper sulphate solution?
Add anhydrous copper sulphate to distilled water.
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 anhydrous copper sulphate reversible?
Anhydrous copper sulfate (CuSO4) is reversible in the sense that it can absorb water molecules from the environment to form hydrated copper sulfate. Conversely, hydrated copper sulfate can be heated to drive off the water molecules, regenerating anhydrous copper sulfate. This process is reversible as it involves only physical changes and not chemical reactions.
Test for presence of water in anhydrous copper sulphate?
To test for the presence of water in anhydrous copper sulfate, heat a small sample of the compound in a test tube. If the compound changes color from white to blue, it indicates that water is present in the compound. This color change happens as the anhydrous copper sulfate absorbs water vapor from the air, converting back into hydrated copper sulfate.
What happens when you heat anhydrous copper sulphate?
Copper sulfate is normally found in the form of blue crystals, copper (II) sulfate pentahydrate. When you heat copper sulfate pentahydrate it turns white as the water which is driven off by the heat. The white solid remaining is anhydrous copper sulfate. If you add water to the anhydrous copper sulfate an exothermic reaction occurs, you can feel the test-tube getting hot, as the blue copper sulfate pentahydrate is re-formed.
What is meant by anhydrous AlCl3?
Anhydrous AlCl3 refers to aluminum chloride that is free from water molecules. It is a dry, solid compound that is commonly used as a catalyst in chemical reactions. Its anhydrous form is important in certain reactions where the presence of water can interfere with the desired outcome.
What happens when water is added to anhydrous copper II sulphate?
When water is added to anhydrous copper (II) sulfate, it will undergo an exothermic reaction where the compound absorbs water molecules to form hydrated copper (II) sulfate. The anhydrous copper (II) sulfate changes color from white to blue as it forms the hydrate.
Why is ethanol treated with anhydrous?
Ethanol isn't "treated" with anhydrous. "Anhydrous" means "without water". Therefore, anhydrous ethanol simply means ethanol without any water molecules in it. It is normally 99.9% ethanol.
