Interpretation Introduction

Interpretation:

The representation, which has the largest percent dissociation of B should be given from the given representations.

Concept Introduction:

Equilibrium expression: The equilibrium expression is equal to the concentration of each product raised to its coefficient in a balanced chemical equation and multiplied together, divides by the concentrate ions of the product of reactants to the power of their coefficient.

Equilibrium constant: Concentration of the products to the respective molar concentration of reactants it is called equilibrium constant. If the K value is less than one the reaction will move to the left side and the K values is higher (or) greater than one the reaction will move to the right side of reaction.

$\text{k}\text{=}\frac{\text{Concentrations}\text{of}\text{Products}}{\text{Concentrations}\text{of}\text{Reactants}}$

$\text{pH}$:

In solution, the negative log of base 10 ${\text{H}}^{+}$ ion concentration is given by $\text{pH}$.

$\text{pH}\text{=}{\text{-log}}_{\text{10}}{\text{[H}}^{\text{+}}\text{]}$

It is used to indicate the acid and basic nature of the solution.
