Chapter 17.3, Problem 27SSC

Interpretation Introduction

Interpretation:

The factors which used to calculate the concentration of the products in reaction mixture is to be listed out.

Concept introduction:

The solubility product constant is the product of the concentration of its dissolved ions raised to the power of their respective stoichiometric coefficients that calculated from the equilibrium reaction.

Answer to Problem 27SSC

There are various factors which is important for the calculation of concentration of products in a reaction mixture which is given as:

a. The initial concentration and represented by I

b. The change in concentration or change in amount from initial state to equilibrium state and represented by C.

c. The equilibrium concentration or amount.

d. Solubility product is also important.

Explanation of Solution

The solubility product constant is the product of the concentration of its dissolved ions raised to the power of their respective stoichiometric coefficients that calculated from the equilibrium reaction.

Consider a generic ionic compound placed in water

$\text{A}\left(\text{s}\right)\underset{}{\rightleftharpoons }\text{bB }\left(\text{aq}\right)\text{ + cC }\left(\text{aq}\right)$

The solubility product constant is

$\text{Ksp = }{\left[\text{B}\right]}^{\text{b}}\text{× }{\left[\text{C}\right]}^{\text{c}}$

$\text{A}\left(\text{s}\right)\underset{}{\rightleftharpoons }{\text{ bB}}^{\text{+}}\left(\text{aq}\right){\text{ + cC}}^{\text{-}}\left(\text{aq}\right)$

I $\text{ = 0 0}$

C $\text{ = }\left(\text{+bx}\right)\left(\text{+cx}\right)$

E $\text{= bx cx}$

There are various factors which is important for the calculation of concentration of products in a reaction mixture which is given as:

a. The initial concentration and represented by I

b. The change in concentration or change in amount from initial state to equilibrium state and represented by C.

c. The equilibrium concentration or amount and represented by E.

d. Solubility product is also important.

Assume the concentration of the solid to be constant. Initial concentration is zero since the solid was yet not placed in water. After reaching the equilibrium, the ions concentration is increasing proportionally to their stoichiometric coefficients, b and c.

So, the solubility product is given as

$\text{ Ksp = }{\left({\left[{\text{B}}^{\text{+}}\right]}^{\text{b}}\text{× }{\left[{\text{C}}^{\text{-}}\right]}^{\text{c}}\right)}^{}$

Conclusion

There are various factors which is important for the calculation of concentration of products in a reaction mixture which is given as:

a. The initial concentration and represented by I

b. The change in concentration or change in amount from initial state to equilibrium state and represented by C.

c. The equilibrium concentration or amount.

d. Solubility product is also important.
