How were the compounds that formed when calcium ion solution was mixed with the anion solutions different from the compounds tha
t formed when barium ion solution was mixed with the anion solutions?
1 answer:
A confirmatory test of sodium hydroxide and potassium chromate can be used to distinguish between a solution of calcium ion and barium ion.
The test for cations can be used to distinguish calcium ion from barium ion.
- Calcium ion (Ca²⁺) forms a white precipitate with a drop of sodium hydroxide which is insoluble in excess.
- Barium ion (Ba²⁺) forms a yellow precipitate with potassium chromate.
Thus, a confirmatory test of sodium hydroxide and potassium chromate can be used to distinguish between a solution of calcium ion and barium ion.

mol times or devided by molar volume
Answer:
Both are the indicators which helps to identity the acid and base
Answer:
2 mol of SO3 produces 1 mol O2
3 mol SO3 produces 3/2 mol of O2
so O2 produced = 1.5(32) =48 gm
