The standard reduction potential of TiO^...

The standard reduction potential of `TiO^(2+)` and `Ti^(3+)` are given by
`TiO_(2+)+2H^(+)+e^(-)toTi^(3+)+H_(2)O" "E^(@)=0.10V`
`Ti^(3+)+3e^(-)toTi" "E^(@)=-1.21V`

Text Solution

Verified by Experts

The correct Answer is:
`-0.8825"volt"`
`TiO^(2+)+2H^(+)+e^(-)toTi^(3+)+H_(2)O,0.1V" "triangleG_(1)^(0)=-2xxFxx0.1`
`Ti^(3+)+3e^(-)toTi-1.21V" "triangleG_(2)^(@)=-3xx(-1.21)xxF`
`TiO^(2+)2H^(+)+4e^(-)toTi+H_(2)O`
`-4xxE^(@)xxF=-1xx0.1xxF+-3xx(-1.21)xxF`
`E^(@)=(0.1-3.63)/(4)=-0.8825"volt"`
