Add 0.40 g of NaOH to 50.0 mL of 0.10 M HCOOH, and find approximate pH. No volume change, Ka HCOOH=1.8x10^-4.

I get pH 8. Right?

  1. I did not get 8. It appears to me that all of the HCOOH is neutralized and there is an excess of NaOH in 50 mL.

    You are given a solution of HCOOH (formic acid) with an approximate concentration of 0.20 M and you will titrate with a 0.1105 M NaOH. If you add 20.00 mL of HCCOOH to the beaker before titrating, approximately what volume of NaOH

    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
