The nickel-cadmium battery spill neutralization uses which solution?

• A. A Solution of Bicarbonate Soda and Water
• B. A Solution of Borax and Water
• C. A Solution of Boric Acid and Water
• D. Vinegar and Water

Answer: (C)

When a nickel-cadmium battery leaks, the electrolyte is typically alkaline potassium hydroxide. To reduce the caustic hazard, you neutralize the base with a mild acid to form water and a salt. Boric acid is used because it is a weak acid that reacts with hydroxide ions in a gentle, controlled way, producing water and potassium borate rather than a vigorous reaction. This minimizes heat, fizzing, and additional corrosion, making cleanup safer. The other options don’t fit as well: a bicarbonate solution is itself basic and won’t neutralize the spill effectively; borax is a basic salt and won’t neutralize the base; vinegar would neutralize, but boric acid provides a milder, safer neutralization with a stable salt as the product.
