Question

In a titration experiment, 20.4 mL of 0.883 M 𝐻𝐶𝑂𝑂𝐻 neutralize 19.3 mL of 𝐵𝑎(𝑂𝐻)2. What is the concentration of the 𝐵𝑎(𝑂𝐻)2 solution?

Do I use M1V1=M2V2? my answer is 0.467, is this correct?

Answer 1

No. You do not use M1V1 = M2V2. That formula works very well for titrations that are 1:1; i.e., say NH3 + HCl ==> NH4Cl. It does NOT work for reactions that are not 1:1: i.e., 2HCOOH + Ba(OH)2 ==> Ba(OOCH)2.
By the way I worked this problem for you yesterday. The answer to day is the same. I will try to find it and post it with a link for you.

Answer 2

Here is my work on the problem yesterday.
