Recipe of the Week – Week 8: Sodium Hydroxide

Continuing our new series of chemical recipes, we bring you week 8 – sodium hydroxide (NaOH).

Remember that when preparing any of our recipes, you should always wear appropriate PPE.

What is sodium hydroxide?

Also known as caustic soda or lye, this is a very corrosive substance that can cause chemical burns, usually used as a solution as these are cheaper and easier to handle, or as a solid. It is highly soluble in water, continuing to absorb moisture until it’s dissolved. It is the most widely used industrial alkali.

Sodium hydroxide is used in papermaking, soap making, the refining of petroleum, and is commonly found in household drain and oven cleaners.
