Question

A student pipets 10.0 0 mL of a 0.100 M solution of reagent Ainto a erlenmeyer flask. Reagent A is then titrated with atitrating solution containing reagent B.  The followingreaction occurs: A + 3B Products It takes the addition of 33.24 mL of the titrating solution (Reagent B) to reach the endpoint. What is the molar concentration of reagent B in the titratingsolution? A student pipets 10.0 0 mL of a 0.100 M solution of reagent Ainto a erlenmeyer flask.

Explanation / Answer

c(reagent A) = n/v n(reagent A) = cV = 0.1 x 0.01 = 0.001mol n(reagent B) = 3 x n(reagent A) = 0.003mol c(reagent B) = n/v = 0.003/0.03324 = 0.09025M Hope this helps!
