Concept explainers
Interpretation:
The correct statement/s needs to be identified.
Concept introduction:
The reaction between an ion and ligand to form a complex ion is called a complex ion formation reaction. The equilibrium constant for formation reaction is called formation constant

Answer to Problem 65QAP
Correct Answer: Option (b) and (e).
Explanation of Solution
Reason for correct option/s:
b. The equation of
Dissociation of the complex,
Equation for two moles of ammonia dissociation is-
Equation for
To produce two moles of water the equation for reaction of two moles of
Equation for
By adding above three equilibrium equation, the net ionic equation for the equilibrium reaction of
Now,
For the reaction of
e. The equilibrium reaction for the formation of
For solution A: Put
The equation for the formation of
For this reaction the formation constant is,
For solution A: Put
Thus, for the complex the ratio of concentration of
Hence, the solution B will have more particles of complex ion per particle of
Reason for incorrect options:
a. Given formation constant
c. The equilibrium reaction of
For the reaction of
d. Reaction with AgI and NaCN form
This reaction occurs in following two steps as follows:
Again,
The value of equilibrium constant (K) is so large that the equilibrium will favor products and overall reaction goes typically to completion.
Reaction of AgI with weak acid HCN forming
Above reaction occurs in following steps-
Again,
The value of K is so large that the equilibrium will favor reactants to an extent that the overall reaction virtually will not takes place. Hence, the statement that one can added either NaCN or HCN as a source of the cyanide ion, to dissolve AgI and fewer moles of NaCN would be required is false.

- Show the mechanism steps to obtain the lowerenergy intermediate: *see imagearrow_forwardSoap is made by the previous reaction *see image. The main difference between one soap and another soap isthe length (number of carbons) of the carboxylic acid. However, if a soap irritates your skin, they mostlikely used too much lye.Detergents have the same chemical structure as soaps except for the functional group. Detergentshave sulfate (R-SO4H) and phosphate (R-PO4H2) functional groups.
