1.	`NH_(4)Cl(s)` is heated in test tube.Vapours are brought in contract with red litmus paper, which changes to blue and then to red.It is because of :A. formation of `NH_(4)OH` and `HCl`B. formation of `NH_(3)` and `HCl`C. greater diffusion of `NH_(3)` than `HCl`D. greater diffusion of `HCl` than `NH_(3)`
Answer» Correct Answer - C Order of the rate of diffusion `NH_(3) gt HCl`. `r prop 1/sqrtM` , where `r`=rate of diffusion and `M`=molecular weight

The heavier elements of groups 13 and 14 besides the group oxidation state exhibit another oxidation state which is two units lower than the group oxidation state and the stability of this lower oxidation state increases down the group. This concept which is commonly called inert pair effect has been used to explain many physical and chemical properties of the element of these groups. Element of group 13A. exhibit oxidation state of `+3` onlyB. form `M^(+)` and `M^(3+)` ionsC. exhibit oxidation states of +1 and +3D. form `M^(-)` and `M^(+)` ions
