MCQ
Conc. ${H_2}S{O_4}$ is diluted
  • A
    By adding water in ${H_2}S{O_4}$
  • ✓
    By adding ${H_2}S{O_4}$ in water
  • C
    By adding glacial acetic acid in ${H_2}S{O_4}$
  • D
    None of the above
✓

Answer

Correct option: B.
By adding ${H_2}S{O_4}$ in water
b
(b) Concentrated ${H_2}S{O_4}$ is diluted by adding the conc. ${H_2}S{O_4}$ in the water drop by drop with constant stirring because it is an exothermic reaction and by doing so heat is generated slowly and dissipated in the atmosphere.
