Calcium metal and Copper(II) Sulfate? | Yahoo Answers

2009-10-2 · When observing a reaction between calcium metal and aqueous copper(II) sulfate I noticed a formation of some sort of gas. When testing the reaction between calcium metal and water I also noticed a formation of gas. I believe this reaction between water and calcium metal caused the formation of diatomic hydrogen and calcium hydroxide. This led me to believe that the gas formed in the reaction

Reactions of Metals | S-cool, the revision website

2019-4-18 · Note: The first three in the table above produce hydroxides and the rest, if they react, produce oxides. The production of the hydroxide (alkali) can be tested by adding universal indior (UI) to the reaction vessel - UI changes from green to purple in the presence of these hydroxides. To test for the release of hydrogen gas, place a lighted splint over the reacting metal - if it ''pops'' then

Why doesn''t magnesium react with water

Al ions are very small due to their high charge-surface area ratio , that''s why they''re so small. these ions gather at surface of the metal and react with O2 in air or water forming Be(O2)2
