Question

A buffer contains significant, equal amounts of propanic acid and its conjugate base.

Which of the following is the chemical equation showing how this buffer neutralizes added acid?

   

CH3CH2CO2H   +   HCl   →   CH3CH2CO2H2+   +   Cl-

   

CH3CH2CH2CO2H    +   H3O+   →   CH3CH2CH2CO2H2+   +   H2O

   

CH3CH2CO2-   +   H3O+   →    CH3CH2CO2H   +   H2O

   

CH3CH2CH2CO2-   +   HCl   →   CH3CH2CH2CO2H   +   Cl- 

   

CH3CH2CH2CO2H    +    CH3CH2CH2OH   →   CH3CH2CH2CO2CH2CH2CH3   +   H2O

Given:

H2SO3(g)       →         H2O (g)        +          SO2 (g)       Keq = 100

What will the numerical value for Keq be for the following reaction?

2 H2SO3(g)       →       2 H2O (g)        +        2 SO2 (g)
