Q5. How to cross verify 0.1 normality H2so4?
Ans. 
To cross verify 0.1 normality H2SO4, use a standard solution of NaOH and an indicator.
• Prepare a standard solution of NaOH of known concentration.

• Add a few drops of an indicator such as phenolphthalein to the H2SO4 solution.

• Titrate the H2SO4 solution with the NaOH solution until the endpoint is reached.

• The endpoint is when the indicator changes color, indicating that all the H2SO4 has reacted with the NaOH.

• Calculate the...read more
