What reagent could be used to separate br- from no3- when added to an aqueous solution containing both?

nai(aq)
agno3(aq)
cuso4(aq)
ba(oh)2(aq)

The correct answer is silver nitrate solution that is .

Explanation:

To separate from ions we will use silver nitrate solution. On addition of silver nitrate solution in a mixture of bromide and nitrate ions.

The silver ion will react with bromide ions to form silver bromide which will get precipitated out as yellow color solid from a mixture.

no reaction

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
