Is copper sulfate and sodium carbonate a chemical change?
Design: We observed four experiments: i) water and copper sulfate ii) iron and copper sulfate solution iii) Sodium Carbonate and copper sulfate solution iv) Hydrochloric acid and magnesium We saw that in Part 1 there was a physical change and in Parts 2, 3, 4 were all chemical change since we couldn’t get the …
Is copper sulfate a physical or chemical change?
Hydrous CuSO4 is not a bond. Therefore, when you heat copper sulfate crystals, the water evaporates leaving behind anhydrous copper sulfate which is white in colour. There are no bonds breaking or forming (the definition of a chemical change) and so it is a physical change.
What type of reaction is sodium carbonate and copper II sulfate?
If you are mixing the solids, there will be no reaction. All you will get is a heterogeneous mixture of the two solids. The mixture of the two white solids is still white. You will get a pale blue-green precipitate.
Is steel wool and copper sulfate solution a chemical or physical change?
Introduction. As shown in the video we have a chemical change because the identity of the substance had changed. When they had added the steel wool to the copper sulfate solution the colour had changed from a dark silver colour to a reddish brownish colour.
What is a physical change vs a chemical change?
Chemical Changes. Physical changes are reversible and do not produce a new substance. Chemical changes result in the production of a new substance and cannot be reversed.
Is copper sulfate and water a physical change?
The dissolution of copper sulfate in water is a physical change whereas that of granulated zinc in dilute hydrochloric acid is a chemical change.
What type of chemical reaction is copper sulfate and steel wool?
when placing a piece of steel wool into a liquid state of copper sulphate,the colour of the solution changes from blue to green, also changing the steel wool into a brown solid, the test tube or the cup will become hot , this is because its an exothermic reaction where the resulting products have less energy then the …
