Question
Chapter 4.4, Problem 1PE
(a)
Interpretation Introduction
Interpretation:
Oxidation number of the given compound and ion has to be assigned.
Concept introduction:
- The number of charges an atom would have in a molecule or ion if electrons were transferred completely is called oxidation number.
Rules in assigning the oxidation number:
- In free state, each atom has zero oxidation number.
- Charge of a monoatomic ion is same as its oxidation number.
- Sum of the oxidation number of neutral compound is zero.
- Group 1, group 2, group 3; has oxidation number +1, +2 and +3 respectively.
- The sum of the oxidation number of atoms in polyatomic ion is equal to the charge of the ion.

Using reaction free energy to predict equilibrium composition
Consider the following equilibrium:
2NO(g) +Cl₂ (g) = 2NOC1 (g) AGº = -41. kJ
Now suppose a reaction vessel is filled with 8.90 atm of chlorine (C12) and 5.71 atm of nitrosyl chloride (NOC1) at 1075. °C. Answer the following questions
about this system:
rise
Under these conditions, will the pressure of NOCI tend to rise or fall?
x10
fall
Is it possible to reverse this tendency by adding NO?
In other words, if you said the pressure of NOCI will tend to rise, can that
be changed to a tendency to fall by adding NO? Similarly, if you said the
pressure of NOCI will tend to fall, can that be changed to a tendency to
rise by adding NO?
yes
no
If you said the tendency can be reversed in the second question, calculate
the minimum pressure of NO needed to reverse it.

Identifying the major species in weak acid or weak base equilibria
The preparations of two aqueous solutions are described in the table below. For each solution, write the chemical formulas of the major species present at
equilibrium. You can leave out water itself.
Write the chemical formulas of the species that will act as acids in the 'acids' row, the formulas of the species that will act as bases in the 'bases' row, and the
formulas of the species that will act as neither acids nor bases in the 'other' row.
You will find it useful to keep in mind that HCN is a weak acid.

0.29 mol of NaOH is added
to 1.0 L of a 1.2M HCN
solution.
