Question
In the balanced equation $aK_2Cr_2O_7 + bHCl \rightarrow cKCl + dCrCl_3 + eCl_2 + fH_2O$:
Answer: A,B,C,D
💡 Solution & Explanation
Balanced: $K_2Cr_2O_7 + 14HCl \rightarrow 2KCl + 2CrCl_3 + 3Cl_2 + 7H_2O$. <br>Cr($+6 \rightarrow +3$) per unit $= 6$. <br>6 Cl ions are oxidized to $3Cl_2$, and 8 Cl ions form salts (acidic action).
