Current Question (ID: 10969)

Question:

$\text{0.284 g of an organic substance gave 0.287 g AgCl in a carius method for the estimation of halogen. The percentage of Cl in the compound is-}$

Options:

1. $5\%$
2. $18\%$
3. $25\%$ (Correct)
4. $33\%$

Solution:

$\text{Hint: } \% \text{ of chlorine} = \frac{35.5}{143.5} \times \frac{\text{amount of AgCl}}{\text{amount of organic compound}} \times 100\%$ $\text{Step 1:}$ $\text{Weight of the organic substance = 0.284 g}$ $\text{Weight of AgCl is = 0.287 g}$ $\text{143.5 g of AgCl contains 35.5 g of chlorine}$ $\text{0.287 g of AgCl contains } \frac{35.5}{143.5} \times 0.287$ $\text{Step 2:}$ $\% \text{ of chlorine} = \frac{35.5}{143.5} \times \frac{\text{amount of AgCl}}{\text{amount of organic compound}} \times 100\%$ $\% \text{ of chlorine is } \frac{35.5}{143.5} \times \frac{0.287}{0.284} \times 100 = 24.98\%$
