If the colours of salts of transition elements are due to the presence of unpaired electrons in the transition metal ions, which of the following ions will be colourless in aqueous solution (The at. no. of T i and F e are 22 and 26 respectively)

Chemistry-General

  1. T i to the power of 3 plus end exponent    
  2. T i to the power of 4 plus end exponent    
  3. F e to the power of 2 plus end exponent    
  4. F e to the power of 3 plus end exponent    

    Answer:The correct answer is: T i to the power of 4 plus end exponentT i to the power of plus 4 end exponent rightwards arrow 3 d to the power of 0 end exponent 4 s to the power of 0 end exponent \ no unpaired e to the power of minus end exponent.
