Question

"You measure 48.9 mL of a solution of sulfuric acid with an unknown concentration, and carefully titrate this solution using a 1.500 M solution of KOH. You find that 34.7 mL of the KOH solution is required to fully neutralize the acid. What is the concentration of the original sulfuric acid solution

Answer 1

C= 0.532M

Step-by-step explanation:

The equation of reaction is

H2SO4 + 2KOH = K2SO4+ H2O

nA= 1, nB= 2, CA= ?, VA= 48.9ml, CB= 1.5M, VB= 34.7ml

Applying

CAVA/CBVB = nA/nB

(CA× 48.9)/(1.5×34.7)= 1/2

Simplify

CA= 0.532M
