Answer:
[tex]B[/tex]
Explanation:
Here, we want to write the formula for the weak base ionization constant for HCO3
Firstly, we write the ionization equation as follows:
[tex]HCO_3^-\text{ + H}_2O\text{ }\leftrightarrows\text{ OH}^-\text{ + H}_2CO_3[/tex]
In writing the constant, we do not add the concentration of water
We have the equation as:
[tex]\frac{[H_2CO_3][OH^-]}{[HCO_3^-]}[/tex]
Thus, the second option is the correct answer choice
