Homework Help: chemistry

Posted by Israel on Monday, March 7, 2011 at 12:26am.

How would you prepare a 150.0mL of a 3.50 pH buffer solution using .500M NaOH and .500M HCOOH. I've gotten the base/acid ratio for the Henderson-H. equation. But now I'm not sure how to figure out the balance of solutions of HCOOH and NaOH to get both 150mL total and still have the ratio between COOH- and HCOOH
