The formation of chlorobenzene from benzene is a SN2 reaction.
Explain the following :
Zinc displaces hydrogen from acid solution [E°Zn+2/Zn =-0.76 volts].
Explain the following :
The hydride of sulphur is a gas but the hydride of oxygen is a liquid.
Find the pH of 0.05 M H2S04 solution.
Given concentration of H2S04 = 0.05 M
H2S04 → 2H+ + SO42-
[H+] = 2[H2SO4]
= 2 x 0.05
= 0.1M pH
= - log [H+]
= -log (0.1)
= 1
∴pH of 0.05 M H2S04 solution is 1.
