How many grams of are required to oxidize of in acidic medium? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
How many grams of $K_2Cr_2O_7$ are required to oxidize $15.2 \text{ g}$ of $FeSO_4$ in acidic medium?
Answer: $4.9 \TEXT{ G}$
💡 Solution & Explanation
$\text{mEq } K_2Cr_2O_7 = \text{mEq } FeSO_4$. <br>$(w/49) \times 1000 = (15.2/152) \times 1000$. <br>$w/49 = 0.1 \Rightarrow w = 4.9 \text{ g}$.
