KCET2011ChemistrySome Basic Concepts of Chemistry
Excess of silver nitrate solution is added to 100 ~mL of 0.01 M pentaaqua chloro chromium (III) chloride solution. The mass of silver chloride obtained in grams is [Atomic mass of silver is 108].
Options
- A287 10⁻³
- B143.5 10⁻³
- C143.5 10⁻²
- D287 10⁻²
Correct answer
A. 287 10⁻³
Step-by-step solution
The reagent is [ Cr ( H ₂ O )₅ Cl ² Cl ₂ . No. of moles of Cl ⁻ ion present aligned &= 2 100 0.01 1000 &=0.002 Mass of AgCl &=0.002 143.5 &=0.287 &=287 10³ ~g aligned
