  • Wow! That is very good for the environment and human safety. But can you explain more on batteries, chemicals and chemical reactions?
  • About 97% of discarded batteries are recycled in Ontario.
  • Did you know?
  • Sure.
  • So the battery is made of sulfuric acid and sodium carbonate (reactant). Once it is recycled water, carbon dioxide and sodium sulfate is produced (product). So it is a neutralization reaction which is a type of double displacement reaction.
  • How can sulfuric acid and sodium carbonate affect the health of workers, or those who live nearby?
  • So, sulfuric acid is a very harmful chemical. It can cause severe issues such as skin burns, irritation in nose and throat, difficulty in breathing, can burn eyes which can cause blindness. Nextly, sodium carbonate is not as toxic as sulfuric acid but can still affect the health. If the chemical is inhaled then it can cause respiratory tract irritation, coughing, shortness of breath and pulmonary edema. So it is very important for the workers to wear Personal Protective Equipment. We also look forward to ergonomics to make sure they don't overstress.
  • How can carbon dioxide and sodium sulfate affect the health of workers, or those who live nearby?
  • Recycling helps in preventing hazardous contents of batteries from polluting the environment.
  • Neutralization reaction- a reaction where where on the reactant side acid and base are combined, on the product side the reactant is destroyed and produces water and salt.Double displacement - exchanging of elements between two compounds
  • It is very important for workers to wear proper personal protective equipment for their safety. Also ergonomics matter too so that the workers do not overstress and make any kind of mistakes during stress. (this is for the reactant side). Also factories are created in open areas, mostly places where no one lives.
