Need help

2. A student pipets 5.00 mL of a 0.125 M solution of reagent A into an Erlenmeyer flask. Reagent A is then
titrated with a titrating solution containing reagent B. The following reaction occurs
A + 3B → Products
It takes the addition of 25.97 mL of the titrating solution (i.e., the reagent B solution) to reach the endpoint.
What is the molar concentration of reagent B in the titrating solution?
14

Expert Solution

Step 1

Recall the given reaction

$A + 3 B \to P r o d u c t s$

$G i v e n t h a t, 5.00 m L o f a 0.125 M s o l u t i o n o f r e a g e n t A i s t i t a t e d w i t h 25.97 m L o f s o l u t i o n B . W e h a v e t o f i n d t h e m o l a r c o n c e n t r a t i o n o f r e a g e n t B i n t h e t i t r a t i n g s o l u t i o n$

Recall the expression of Molarity

$M o l a r i t y = \frac{(m o l e s o f s o l u t e) \times 1000}{V o l u m e o f s o l u t i o n (i n m L)}$
