now I calculated the Molarity to be 0.174 M I THINK thats the initial because it comes from the 32.9g and I dont beleive this is a strong acid. So my equation is HCOOH + H2O <> H3O + HCOO- SO the initial concentrations would be HCOOH =0.174 H3O...
Answer:
Since it's a weak organic acid-You must use the Ka value and mass action expression to find [H+] Ka...

An aqueous solution of barium hydroxide has a pH of 9.78 at 25*C. Calculate the concentration of the base. Could someone please explain these two questions to me. Thanks.
Answer:
pH = 9.78 which mean the pOH = 14 - 9.78 = 4.22 This means the [OH] = 1x10^-4.22 or more conventionally...
