Consider two solutions:1. ) 0.5 M NaCl aqueous solution at 25°c ; NaCl is completely ionisedNacl 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/arecorrect? |

Answer» 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
5
COOH in benzene at 25 o C; C 6
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 5
COOH associate to give one DIMER (particles). |
