Explain CuSO4.5H2O is blue Explain CuSO4.5H2O is blue while CuSO4 is colourless ?while CuSO4 is colourless ?

Answer: We have 1 mole of CuSO4 contains 1 mole of copper. Molar mass of CuSO4 = Atomic mass of [Cu × 1 + S × 1 + O × 4 ] =(63.5) + (32.00)...

Solution: For an m×n chessboard there are 2m+2n−2 ways. Case I. There are two horizontally adjacent squares of the same color: 2m−2 ways. Case II. There are two vertically adjacent squares of the same color: 2n−2 ways. Case III. None of the...

(i) Yes  (ii) No

[Hint : NaCl + H2SO4 (conc.)->  NaHSO4 + HCl]

CuSO4 does not has any ligand, so splitting of d-orbital take place while CuSO4.5H2O has water ligand.

[Ti(H2O)6]3+ : In this core Ti+3 has one unpaired e- while Sc+3 does not has any unpaired electron.

The correct answer is (B) CuSO4

This is because of scattering of light. Light from the Sun near the horizon passes through larger distance in the earth’s atmosphere before reaching our eyes. So, most of the...

(a) Iron rod is immersed in it. When the iron rod is inserted in copper sulphate solution, iron being more reactive than copper displaces it and iron sulphate will be...
