1. Answer:

   0.685

   Explanation:

   The original of 0.5N HCl solution of 1 litre had 18.225 gm of HCl

   Initially 18.225gm of HCl was dissolved in 1 liter of solution

   After heating , mass of HCl dissolved in the reduced 600mL of solution was found to be (18.225−3.25)gm=14.975 gm

   Hence

   Normality of new solution=

   Volume of solution in litre

   Equivalent weight of HCl mass

   N=

   1000mL per litre

   600mL

   Equivalent weight of HCl

   14.497

   N=

   0.6 litre

   36.45

   14.497

   N=

   0.6 litre

   0.3977 Meq

   N=0.685
