The number of electrons required to balance the charge in the following half-equation is: — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Calculate the net charge on both sides. Left side: $(-1) + 4(+1) = +3$ . Right side: $0 + 0 = 0$ . To balance the charge, we must add 3 electrons ( $3e^-$ ) to the more positive side, which is the left side.
