The ratio of amounts of

{\mathrm{H}_2}\mathrm{S}

needed to precipitate all the metal ions from 100 mL of 1 M

\mathrm{AgN}{\mathrm{O}_3}

and 100 mL of

\mathrm{CuS}{\mathrm{O}_4},

will be

View answer and explanation

Correct option: B

1\mathrm{ }:\mathrm{ }2

Option B (

1\mathrm{ }:\mathrm{ }2

) is correct because

AgNO_3

requires 1 mole of

H_2S

per mole of

AgNO_3

while

CuSO_4

requires 1 mole of

H_2S

per mole of

CuSO_4

, and since the molarity and volume are the same, the ratio is 1:2.
