Question

What are the major species present when dissolved in water:

C6H12O6 -

FeBr3 -

C3H8O3 -

Answer 1

1. Glucose(C6H12O6) is itself major species. It is non electrolyte. SO glucose and H₂O major species.
2. FeBr₃ ionises to Fe⁺³ and Br^- . so both ions Fe⁺³ and Br^- are major species.
3. C3H8O3 (glycerol) is non electrolyte and so itself and water both are major species it is dissolved in water.

Strong eletrolytes ionise cosiderably into ions and these ions will be major species.

when weak acidor base dissolved in water , the cojugate acid/base will be major species.

non electrolytes dissolved in watr , then itself and water will be major species.

majoe species is 10% more compared to other species in the water
