Using barium chloride solution, how will you identify which bottle contains H2SO4 out of three bottles containing HCl, H2SO4 and HNO3, respectively?
To identify which bottle contains H2SO4 using barium chloride solution, we can follow these steps:
- Add a few drops of barium chloride solution to a small amount of each acid in separate test tubes.
- If H2SO4 is present, a white precipitate of barium sulfate (BaSO4) will form in the test tube containing H2SO4.
- The test tube containing HCl or HNO3 will not show any reaction with the barium chloride solution.
Therefore, the bottle containing H2SO4 can be identified by the formation of a white precipitate of barium sulfate in the test tube containing the acid.
