Question

A 0.250 L buffer is made of 0.350 M [NaH2Po4] and 0.255M [Na2HPO4].

a. what is pH of this buffer?

b. What is pH of this buffer after 0.012 mols of HCl is added?

Please show work and all steps!!!!

Answer 1

Answer #1

Molarity of NaH2Po4 Molarity of Na2HPo4 We know, Moles Molarity (M) x Volume (V in L) 0.350 M So Moles NaH2Po4 * 0.250 mol 0.

A buffer consists of 0.24 M NaH2PO4 and 0.47 M Na2HPO4. Given that the K values for H3PO4 are, Ka1 = 7.2 x 10-3, Ka2 = 6.3 x 10-8, and Ka3 = 4.2 x 10-13, calculate the pH for this buffer. I know that the answer is 7.49 because pH = -log(6.3 x 10-8) + log(0.47/0.24). What I want to know is WHY 6.3 x 10-8 was used instead of Ka1 or Ka3. Thanks.
