Which equation is used to relate pH, pKa, and the ratio of conjugate base to acid in a buffer solution?

• Nernst Equation

• Van't Hoff Equation

• Arrhenius Equation

• Henderson-Hasselbalch Equation

In the Henderson-Hasselbalch equation, what happens to the equation when the moles of acid and conjugate base are equal?

• The pH is double the pKa

• The pH is equal to the pKa

• The pH is half the pKa

• The pH is unrelated to the pKa

What is the formula to calculate Ka from a given pKa value?

• Ka = 10^pKa

• Ka = pKa^10

• Ka = 10^-pKa

• Ka = -10^pKa

If a pKa value is 4.19, what is the approximate range for the Ka value?

• Between 1x10^-4 and 1x10^-5

• Between 5x10^-5 and 8x10^-5

• Between 8x10^-4 and 5x10^-4

• Between 1x10^-5 and 1x10^-6

When rounding 4.19 to estimate Ka, which two whole numbers are used to find the range?

• 3 and 4

• 4 and 5

• 5 and 6

• 6 and 7

What is the estimated Ka value when pKa is rounded to 4.2?

• 7x10^-5

• 8x10^-5

• 6.46x10^-5

• 5x10^-5
