C They react with carbonates producing carbon dioxide. It lies in the middle of the reactivity series.Because of lesser reactivity, the reaction of Al with acid is not so vigorous as compared to the most reactive metals in series. Aluminium dissolves readily in dilute sulphuric or hydrochloric acid under the formation of Al(III) and hydrogen H 2. iii. The reaction is similar to the reaction with water, forming the metal salt (either sulfate or chloride) plus H 2(g). Aluminum reacts slower then similar metals such as Magnesium or Zinc because of an Aluminum Oxide (Al2O3) layer. Metal 'B' is attracted by magnet. 1 Answer +1 vote . But when the thin, outer oxide layer gets dissolved in acid,, then fresh aluminium metal is exposed which reacts rapidly with dilute hydrochloric acid. Soluble metal oxides and hydroxides are called alkalis, and react with acids in solution.

If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. For example. Place about 5cm depth of the acid in each of the five test tubes; Place a small piece of each of … The met­al dis­solves in hy­drochlo­ric acid, yield­ing alu­minum chlo­ride and col­or­less hy­dro­gen gas. The dilute acid has to break down the Al2O3 where as in some other reactions this process is not necessary. Magnesium is a metal that will react with hydrochloric acid. The balanced equation is = 2Al(s) + 6HCl(aq) -----> 2AlCl3(aq) + 3H2(g). The reaction between an insoluble metal oxide and a dilute acid is often quite slow so it is possible to observe the progress of the reaction as the solid reactant ... 5. 19 Three solids, P, Q and R, all react with dilute sulfuric acid to produce zinc sulfate. chemical reactions and equations; class-10; Share It On Facebook Twitter Email. 18 Concentrated aqueous sodium chloride, concentrated hydrochloric acid and molten lead bromide were separately electrolysed in experiments 1, 2 and 3. platinum electrodes concentrated aqueous sodium chloride experiment 1 experiment 3 platinum electrodes concentrated hydrochloric acid experiment 2 d.c. power supply lamp LEAD BROMIDE TOXIC heat 2 Al (s) + 3 H 2 SO 4 (aq) 2 Al 3+ (aq) + 2 SO 4 2− (aq) + 3 H 2 (g) [2] 2 Al (s) + 6 HCl (aq) 2 Al 3+ (aq) + 6 Cl − (aq) + 3 H 2 (g) [2] Reaction of aluminium with air.
