Re:buffer solution H3PO4 and HPO4-- « Reply #8 on: May 10, 2005, 08:12:03 AM » May be at pH 3.95 a buffer H3PO4/NaH2PO4 exists that contain 0.2 M H3PO4 and we should increase pH to 7.30 by adding Na2HPO4, but this is only my guess Logged AWKAlbert Lonely Wander...
NaH2PO4 is mixed with 100 mL of 0.1 M H3PO4, what is the pH of the buffer mixture? The pKa of H3PO4 is 2.1. Acidic Buffer Solution:Let us assume the addition of a small amount of acid or base to a buffer solution. The...
wondering if somebody could help explain to me how does the reaction of nacl + H3PO4 form nah2po4 and hcl gas? i thought h3po4 was a weaker acid than hcl, so how can it form a stronger acid? and does it depend on the strength of h3po4 used?
A buffer solution contains 0.432 M NaH2PO4 and 0.341 M Na2HPO4. Determine the pH change when 0.107 mol NaOH is added to 1.00 L of the buffer. A solution contains 0.25 M HA (Ka = 1.0 x 10-6) and 0.45 M NaA. What is ...
