She waits until they have formed the two layers, then puts an alka seltzer tablet in the bottle. Bubbles form and the water begins to fizz. This is because the baking soda and acid that make up the tablet react when the hit the water, which causes the effervescence. The bubbles that form slowly float up through the oil, making the lava lamp effect.]]> 2017-02-28 19:01:04 UTC https://padlet.com/lindseycooper2021/4rchtsp7iqnf/wish/156832670 rglieberman2021 https://padlet.com/lindseycooper2021/4rchtsp7iqnf/wish/156833222 In this chemical reaction, calcium oxide (quicklime), a white solid, and water are the reactants and calcium hydroxide (slaked lime) is the product.

It looses the final water molecule at 200° celsius, and because it no longer has water molecules, it becomes a new substance of anhydrous copper sulfate, or copper sulfate without water. The lack of water in copper sulfate results in the blue color becoming white.
