Use the following equilibrium reaction and constant for the deprotonation of bicarbonate (hco3-) to carbonate (co32-) to determine: hco3 = co2 + h+ k = 10-10.33 (a) whether hco3 or co32- would dominate at ph 9.1 and (b) what the concentration of [co32-] would be at this ph if [hco3 ] = 10-6 m

For a: will dominate at pH = 9.1

For b: The concentration of carbonate ions at pH = 9.1 will be

Explanation:

To calculate the pH of the solution, we use the equation:

    ......(1)

We are given:

pH = 9.1

Putting values in equation 1, we get:

For the given chemical equation:

The expression of for above reaction follows:

Putting value of hydrogen ion concentration in above equation, we get:

Hence, will dominate at pH = 9.1

The expression of for above reaction follows:

We are given:

Putting values in above equation, we get:

Hence, the concentration of carbonate ions at pH = 9.1 will be

your answer would be “dry”
