Three flasks A, B and C respectively contain 0.1 M, 0.1 m and 0.1 N aqueous HC1
solutions, prepared at 40°C. Considering the density of water = 1 &/CM³ at 4⁰C,
which of the following statements is/are correct ?
a. Concentration of all three solutions is exactly the same.
b. Concentration of HCL in flask A and flask C is exactly the same.
c. Concentration of HCL in flask B is lesser than concentration of HCL in flasks A
and C.
d. No two flasks have HCl of exactly the same concentration.

Match the columns :
Group I                                       Group II
a. Surfadants                            I. Alkylaryl sulphonates
b. Dye intermediates                II. Benzene
c. Lacquers                              III. Cellulose acetate
d. Solvents                               IV. Ethyl acetate
                                                 V. Anthracene
