When the first reaction equation is:
AgI(S) ↔ Ag+(Aq) + I-(Aq)
So, the Ksp expression = [Ag+][I-]
∴Ksp = [Ag+][I-] = 8.3 x 10^-17
Then the second reaction equation is:
Ag+(aq) + 2NH3(aq) ↔ Ag(NH3)2+
So, Kf expression = [Ag(NH3)2+] / [Ag+] [NH3]^2
∴Kf = [Ag(NH3)2+] /[Ag+] [NH3]^2 = 1.7 x 10^7
by combining the two equations and solve for Ag+:
and by using ICE table:
AgI(aq) + 2NH3 ↔ Ag(NH3)2+ + I-
initial 2.5 0 0
change -2X +X +X
Equ (2.5-2X) X X
so K = [Ag(NH3)2+] [I-] / [NH3]^2
Kf * Ksp = X^2 / (2.5-2X)
8.3 x 10^-17 * 1.7 x10^7 = X^2 / (2.5-2X) by solving for X
∴ X = 5.9 x 10^-5
∴ the solubility of AgI = X = 5.9 x 10^-5 M
Am not exactly sure but i think ots conduction
I'll just list down the acidic, basic, and neutral salts.
ACIDIC
<span>THE CATION: is the conjugate acid of a weak base
THE ANION: Conjugate Base of A Strong Acid
</span>Ammonium Sulfate - <span>(NH₄)₂SO₄
</span>Ammonium Chloride - NH₄Cl
BASIC
<span>THE CATION: comes from the cation of a strong Base (i.e. Na+, K+, Li+)
The Anion: comes from the conjugate base of a weak acid
</span>Sodium Acetate - CH₃COONaSodium Phosphate - <span>Na₃PO₄
</span>Calcium Acetate - (CH₃COO)₂Ca
NEUTRAL
<span>THE CATION: comes from a strong base
THE ANION: comes from a strong acid
</span>Sodium Nitrate - NaNO₃
Barium Chloride - BaCl₂Potassium Chloride - KCl
The symbol for copper is CU, which means copper cuprum, the Latin word for copper.
Average kinetic molecular energy is actually defined by temperature, so any gas, no matter the volume or pressure, will have the same average kinetic molecular energy as long as its temperature is the same. Therefore, Gases A, B, and D all have the same average molecular kinetic energy, since they are at 12<span>°C.</span>
