Question

47.0ml of a HBr solution were titrated with 37.5ml of a 0.215M LiOH solution to reach the equivalence point. what is the molarity of the HBr solution

Answer 1

0.172

Step-by-step explanation:

Answer 2

Hello!

The molarity of the HBr solution is 0,172 M.

Why?

The neutralization reaction between LiOH and HBr is the following:

HBr(aq) + LiOH(aq) → LiBr(aq) + H₂O(l)

To solve this exercise, we are going to apply the common titration equation:

`M1*V1=M2*V2`

`M1=(M2*V2)/(V1)= (0,215 M * 37,5 mL)/(47 mL)=0,172 M`

Have a nice day!
