While doing an experiment a student observed that the blue colour of the aqueous copper sulphate

Iron nails become reddish brown in colour and solution becomes green in colour.

A die has six faces that are numbered from 1 to 6, with one number on each face. Let us denote the red, white, and blue dices as R, W,...

Because water molecules act as ligands and results in crystal Fleld splitting of d-orbitals of Cu2+ ion.

The colour of ferrous sulphate crystals is green. On heating, FeSO4.7H2O first decomposes to form anhydrous ferrous sulphate (FeSO4) which is white in colour.

The correct answer is (D) D

A die has six faces that are numbered from 1 to 6, with one number on each face. Let us denote the red, white, and blue dices as R, W,...

i. a. Initial colour of the copper sulphate solution was blue. b. After completion of reaction,colour  of the solution changes to light green. ii. In this reaction,colour of solution changes from blue...

Aluminium sulphate is colourless and it does not undergo any change as iron does not react with it. Copper sulphate solution is blue which changes into green due to the...

i. When excess of aqueous KCN is added to an aqueous solution of copper sulphate, the coordination entity formed is [Cu(CN)4]2 -. [Cu(H2O)4]2+ + 4CN -  →   [Cu(CN)4]2 -  + 4H2O ii. [Cu(CN)4]2- is...
