Question

a water Sample is alkaline to both phenolpthalein as well as methyl orange 100 ml of the water sample on titration with N/50 H2So4 required 4.9 ml of the acid to phenolphthalein end - point. when a few drops of methyl
orange are added to the same
Solution and
the titration further Continued, the yellow
Colour of the
Solution just turned red
aften red addition of another 10.8ml of
the acid solution . Elucidate the type and
extent of alkalinity present in the water
Sample. ​

Answer 1

100 ml of the water sample on titration with N/50 H2So4 required 4.9 ml of the acid to phenolphthalein end - point. when a few drops of methyl

orange are added to the same

Solution and

the titration further Continued, the yellow

Colour of the

Solution just turned red

aften red addition of another 10.8ml of

the acid solution . Elucidate the type and
