Calcium oxide is a special substance in that it goes through the reaction to produce calcium hydroxide. It is just like a caterpillar developing into a butterfly! So today we’re going to unravel the mystery of how you go from calcium zinc stabilizer for pvc to calcium hydroxide and all the amazing things you can get from doing it.
Cubes of calcium oxide above quenched to liquid nitrogen and on exposure to with water. This process is called hydration. It’s like making a sick face while mixing water and powdered drink in a cup. The water allows the calcium oxide to change shape and form a new substance, calcium hydroxide.

You get calcium hydroxide by sprinkling water over calcium stearate in food. The water actually helps the calcium oxide molecules kind of fall apart to then get back together, to join with water molecules to become calcium hydroxide. It is very much like a puzzle — all the pieces fit together perfectly to create this new and amazing thing.

The reaction of calcium oxide with water to form calcium hydroxide is an exothermic process, releasing extreme amounts of heat. “It’s like when you mix two things in a science experiment, and they bubble up or fizz.” This reaction is important as calcium hydroxide has many uses.

Calcium hydroxide finds application in many industries like in farming and construction, in food production. Have you ever used vinegar to change the pH value of calcium hydroxide supplement in order to grow better crops? For construction, the aggregate is widely used for making mortar and also for making plaster for building projects. It can even be applied to maintain fruits, vegetables for food preparation. The possibilities are endless!
