Question

Calculate the pH of a solution made by mixing 15.0 cm3 0.1M NaOH and

35.0 cm3 0.2M HCOOH. [Ka = 1.82 x 10-4 M]​

Answer 1

Answer:

Therefore, pH of this buffer solution is 4.74. Originally Answered: How do I determine the pH of a buffer? Example - you have a buffer that is 0.30 M in CH3COONa and 0.20 M in CH3COOH. pKa CH3COOH = 4.74 .
