Photographers' Formulary 5lbs Sodium Hydroxide, Hazmat

It is essential to understand the versatile nature of Sodium Hydroxide, a high-energy accelerator or alkali, often utilized to activate low-energy developing agents like hydroquinone. This potent compound is a caustic alkali, frequently employed in situations where a robust and rapid-acting developer is needed. However, it's important to note that developers mixed with this caustic alkali may have limited shelf life and can exhaust quickly.

Sodium Hydroxide, also known as a key ingredient in many commercial drain cleaners, is one of the most caustic chemicals commonly found in black & white darkroom operations. It's crucial to handle this product with care due to its highly reactive nature.

Storage is another critical aspect of this product. It is recommended to store Sodium Hydroxide in a well-sealed container to prevent exposure to air, as it can absorb moisture rapidly, leading to a change in its weight.

In summary, Sodium Hydroxide is a powerful and versatile chemical with various applications, from activating developing agents to being a primary component in commercial drain cleaners. However, due to its caustic nature, it requires careful handling and storage.
