Lead glass Lead yellow and lead red. In addition to being the main application for lead metal, lead–acid batteries are also the main consumer of lead compounds. The energy storage/release reaction used in these devices involves lead sulfate and lead dioxide: Pb (s) + PbO 2 (s) + 2 H 2 SO 4 (aq) → 2 PbSO 4 (s) + 2 H 2 O (l)
Lead may be found in food when food is grown in soil that is high in lead, airborne lead contaminates the crops, animals eat lead in their diet, or lead enters the food either from what it was stored or cooked in.
