Answer:

the salt that has the highest solubility is

(a) AV

∴ S = 1 M

Explanation:

a) AV ↔ A+  + V-

    S        S       S

⇒ Ksp = [ A+ ] * [ V- ] = S * S = S²

⇒ S = √ Ksp

b) B2W ↔ 2B+  +  W2-

     S           2S        S

⇒ Ksp = [ B+ ]² * [ W2- ] = ( 2S )² * S = 4S³

⇒ S = ∛ (Ksp / 4)

c)  C2X3 ↔ 2C3+  +  3X2-

        S          2S          3S

⇒ Ksp = [ C3+ ]² * [ X2- ]³ = (2S)² * (3S)³ = 4S² * 27S³ = 108S∧5

⇒ S = ( Ksp / 108 )∧(1/5)

d) DY2 ↔ D2+  +  2Y-

     S           S         2S

⇒ Ksp = [ D2+ ] * [ Y- ]² = S * (2S)² = 4S³

⇒ S = ∛ ( Ksp / 4 )

e) EZ3 ↔ E3+  +  3Z-

     S          S         3S

⇒ Ksp = [ E3+ ] * [ Z- ]³ = S * (3S)³ = 27S∧4

⇒ S = ( Ksp / 27 )∧(1/4)

assuming that Ksp = 1

a) S = √1 = 1

b) S = ∛(1/4) = 0.63

c) S = ( 1 / 108)∧(1/5) = 0.392

d) S = ∛ ( 1/4 ) = 0.63

e) S = ( 1 / 27 )∧(1/4) = 0.438

anyanavicka [17]

Answer:

c. precipitation

Explanation:

Let's consider the following balanced net ionic equation.

Cl⁻(aq) + AgNO₃(ag) ⇒ AgCl(s) + NO₃⁻ (ag)

What kind of reaction is this?

a. acid-base. No, because the reactants are not acids and bases.

b. redox. No, because all the species have the same oxidation numbers in the reactants and the products

c. precipitation. Yes, because an insoluble compound (AgCl) is produced, which then precipitates.
