Try your hand at writing these kinds of equations by considering the reactions that the metals Na and Ca have with water. From their position on the periodic table, you can tell that Na and Ca form the ions Na + and Ca 2+. Check your

Reactions of Metals | S-cool, the revision website

2019-4-27 · 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

14.5: Reactions of Acids and Bases - Chemistry …

For example, zinc metal reacts with hydrochloric acid producing zinc chloride and hydrogen gas. \[\ce{Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)}\] Bases react with certain metals like zinc or aluminum for example to also produce hydrogen gas. Sodium hydroxide reacts with zinc and water to form sodium zine and hydrogen gas.
