Hey there! Do you know what sodium is? It's a type of element, kind of like a Lego block that scientists use to put together other things.
Well, sodium cyanoborohydride is a special type of Lego block that scientists use to help make other things in chemistry.
When scientists want to make a new molecule, they need to add different pieces together. And sometimes they need a special piece to help it all stick together. That's where sodium cyanoborohydride comes in! It's like a glue that helps other pieces stick together.
But why is it called "cyanoborohydride"? "Cyano" means a special group of atoms that stick together in a certain way, "borohydride" means another special group of atoms, and sodium is just the name of the element that the glue is made of.
Sodium cyanoborohydride is helpful in making all sorts of things, like medications and plastics. Scientists need to be very careful with it, though, because it can be dangerous when it's not used properly.
Does that help you understand what sodium cyanoborohydride is?
