`K_(2)Cr_(2)O_(7)+HCl to KCl +CrCl_(3)+H_(2)O+Cl_(2)`

Text Solution

AI Generated Solution

To balance the equation \( K_2Cr_2O_7 + HCl \rightarrow KCl + CrCl_3 + H_2O + Cl_2 \) using the oxidation number method, we will follow these steps: ### Step 1: Assign Oxidation Numbers - **Potassium (K)**: +1 - **Chromium (Cr)** in \( K_2Cr_2O_7 \): Let it be \( x \). The equation for the oxidation state of chromium in \( K_2Cr_2O_7 \) is: \[ 2(+1) + 2x + 7(-2) = 0 \implies 2 + 2x - 14 = 0 \implies 2x - 12 = 0 \implies x = +6 \] ...
