Equivalence Point Calculator

Calculate the pH and volume at the equivalence point for acid-base titrations

Equivalence Point Parameters

Titration Type:

Acid Concentration (M)

Acid Volume (mL)

Base Concentration (M)

Ka of Weak Acid

pH at Equivalence Point

8.72

Solution is Basic

Equivalence Volume

50.0000 mL

pOH

5.28

Total Volume

100.00 mL

Conjugate Concentration

At Equivalence Point:

Conjugate base hydrolyzes

Strong + Strong

pH = 7 (neutral salt)

Weak Acid + Strong Base

pH > 7 (basic conjugate)

Strong Acid + Weak Base

pH < 7 (acidic conjugate)
