Question

consider two solutions:
1. ) 0.5 M NaCl aqueous solution at 25°c ; NaCl is completely ionised
Nacl is completely jonized.
2.) 2.0 MCH5coot in benzene at 25°c ;
the acid dimerizes to the full extent.
which of the following statement (s) is/are
correct?​

Answer 1

Answer:

0.5 M NaCl aqueous solution at 25

o

C; NaCl is completely ionized. 1 L of solution will contain 1L×0.5mol/L×2=1.0mol of particles as one molecule of NaCl dissociate to give two ions (particles).

II. 2.0 M C

6

H

5

COOH in benzene at 25

o

C; C

H

5

COOH dimerizes to the full extent. 1 L of solution will contain 1L×2.0mol/L×0.5=1.0mol of particles as two molecules of C

6

H

COOH associate to give one dimer (particles).
