If ionised in an aqueous solution, then the value of van’t Hoff factor is:
1.24 g of (molar mass 124 g mol) is dissolved in 1 kg of water to form a solution with boiling point of 100.105°C, while 2.54 g of AY_2 (molar mass 250 g mol) in 2 kg of water constitutes a solution with a boiling point of 100.026°C. = 0.52 K kg mol. Which of the following is correct?
Antibody | Description |

P. IgE | (i) Cross the placenta |
Q. IgG | (ii) Dominant antibody produced in immune responses |
R. IgM | (iii) It is found in the mother's milk |
