Ni(OH)₂ ⇄ Ni⁺² + 2 OH⁻
Ksp = [Ni⁺²][OH⁻]² = S (2S)² = 4S³
where S is molar solubility.
at pH = 10
[H⁺] = 10⁻¹⁰
[H⁺][OH⁻] = 10⁻¹⁴
so [OH⁻] = 10⁻⁴ M
Ksp = S [10⁻⁴ + 2S]²
Ksp is very small so the molar solubility of OH⁻ will be very small
so (10⁻⁴ + 2S) is about 10⁻⁴
so Ksp = S x 10⁻⁸
S =
= 6 x 10⁻⁸ M
Ksp = [Ni⁺²][OH⁻]² = S (2S)² = 4S³
where S is molar solubility.
at pH = 10
[H⁺] = 10⁻¹⁰
[H⁺][OH⁻] = 10⁻¹⁴
so [OH⁻] = 10⁻⁴ M
Ksp = S [10⁻⁴ + 2S]²
Ksp is very small so the molar solubility of OH⁻ will be very small
so (10⁻⁴ + 2S) is about 10⁻⁴
so Ksp = S x 10⁻⁸
S =
Answer:
a) Both chairs conformers have one of its substituents in an axial position and the other in an equatorial position
b) One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position
c) One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position
d) Both chairs have one of its substituents in an axial position and the other in an equatorial position
e) Both chairs have one of its substituents in an axial position and the other in an equatorial position
(f) One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position
Explanation:
Determine what the substituents would be
a) Cis-1,2- : Both chairs conformers have one of its substituents in an axial position and the other in an equatorial position
b) Trans-1,2- : One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position
c) Cis-1,3- : One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position
d) Trans-1,3- : Both chairs have one of its substituents in an axial position and the other in an equatorial position
e) Cis-1,4- : Both chairs have one of its substituents in an axial position and the other in an equatorial position
(f) Trans-1,4- : One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position
