Tiny Science Amazing Precipitation Chemical Reaction | Make Science Fun

G'day,

I'm Jacob from Make Science Fun.

Today, I'm doing the classic lead iodide precipitation reaction.

Oh wow!

In the glass below,

I've got a clear colorless solution of potassium iodide,

and now I release into it a clear,

colorless solution of lead nitrate.

Both potassium iodide and lead nitrate are soluble in water,

but when they mix together,

they form an insoluble

precipitate

called lead iodide.

The yellow lead iodide forms a suspension

and slowly sinks to the base.

Well,

thanks so much for joining me today.

And I'll see you guys soon.

Bye.
