Question

Which is the incorrect statement?

  1. The heat of hydration of the dipositive alkaline earth metal ions decrease with an increase in their ionic size
  2. NaNO3 forms Na2O on heating 
  3. Hydration of alkali metal ion is le than that of II A
  4. Alkaline earth metal ions, because of their much larger charge to size ratio, exert a much stronger electrostatic attraction on the oxygen of water molecule surrounding them

The correct answer is: NaNO3 forms Na2O on heating
