Sodium Hypophosphite[edit]

Sodium hypophosphite is a chemical compound with the formula NaPO₂H₂. It is the sodium salt of hypophosphorous acid and is commonly used as a reducing agent in various chemical reactions, particularly in the electroless plating of metals.

Chemical Properties[edit]

Sodium hypophosphite is a white crystalline solid that is highly soluble in water. It is a powerful reducing agent and is often used in chemical processes that require the reduction of metal ions to their metallic state. The compound is stable under normal conditions but can decompose when heated, releasing phosphine gas.

Uses[edit]

Sodium hypophosphite is primarily used in the electroless nickel plating process, where it serves as a reducing agent to deposit nickel onto a substrate without the use of an external electrical current. This process is widely used in the electronics industry for coating printed circuit boards and other components.

In addition to its use in plating, sodium hypophosphite is also employed in the synthesis of various pharmaceuticals and as a catalyst in certain chemical reactions.

Safety and Handling[edit]

Sodium hypophosphite should be handled with care, as it can release toxic phosphine gas upon decomposition. It is important to store the compound in a cool, dry place and to use appropriate personal protective equipment when handling it.
