What volume of a 0.00945-m solution of potassium hydroxicce would be required to titrae 50.00ml of a sample of acid rain with a h2so4 concentration of 123 x 10-4 m
h2so4 + 2koh ? k2so4 + 2h2o

The volume of HBr solution required is 130.16 mL

Explanation:

To calculate the concentration of base, we use the equation given by neutralization reaction:

where,

are the n-factor, molarity and volume of acid which is

are the n-factor, molarity and volume of base which is

We are given:

Putting values in above equation, we get:

Hence, the volume of KOH solution required is 130.16 mL
