What solution should be used to neutralize nickel-cadmium battery cases affected by electrolyte?

The appropriate solution for neutralizing nickel-cadmium battery cases affected by electrolyte is boric acid. This is because nickel-cadmium batteries contain alkaline electrolyte solutions, primarily potassium hydroxide. When the electrolyte comes into contact with surfaces, it can create a hazardous situation.

Boric acid is an effective neutralizer for alkaline substances. When applied, it can counteract the effects of the alkaline electrolyte found in nickel-cadmium batteries. Unlike stronger alkaline substances such as sodium hydroxide, boric acid is less corrosive and safer to handle, making it a suitable choice for this particular application. It not only helps in neutralizing the pH but also can aid in cleaning the affected surfaces without causing additional damage.

Using alternatives like sodium bicarbonate could also neutralize some acids but may not be as effective in directly addressing alkaline electrolyte issues, which can be more persistent than acidic contaminants. Thus, while sodium bicarbonate is a common neutralizing agent for certain types of battery leaks, boric acid is specifically chosen for nickel-cadmium batteries due to its effectiveness against alkaline environments.
