6. The of formic acid is pKa 3.750. What is the Ka of formic acid?
To calculate the Ka of formic acid, we need to use the formula:
Ka = 10^(-pKa)
Given that the pKa of formic acid is 3.750, we can plug this value into the formula:
Ka = 10^(-3.750)
Ka = 1.778 x 10^(-4)
Therefore, the Ka of formic acid is approximately 1.778 x 10^(-4).
