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

Reactions of Group 2 Elements with Acids - Chemistry

Calcium sulfate is slightly soluble, and strontium and barium sulfates are essentially insoluble. When exposed to sulfuric acid, a layer of insoluble sulfate is formed on each of these metals, slowing or stopping the reaction entirely. In the calcium case, some hydrogen is produced, along with a white precipitate of calcium sulfate.
