Curiousity Questions:

Alyson:

Are their any side affects of Calcium Oxide/Calcium Hydroxide when one consumes it?

• The intake of Calcium Hydroxide can cause an upset stomach. It causes significant damage/irritation to your gastrointestinal tract. This results in side affects such as nausea, vomiting or severe abdominal pain.

Is their a reaction created when Calcium Oxide is combined with Calcium Carbonate?

•  Yes. When Calcium Oxide and Calcium Carbonate mix, they create a form called Calcium Carbonate.

Keisha:

• When released into the environment, calcium oxide reacts with water to create calcium hydroxide. Severe effects calcium hydroxide has had on the environment are considered to be caused by pH changes. Calcium hydroxide is considered not to be harmful to the environment.

• Calcium oxide is identified as a corrosive material, exposure to the chemical can effect the body if it is inhaled, comes in contact with your eyes or skin, or is digested. severe burns may also be a result with long-term exposure of Calcium oxide.
