Reaction With Dilute Acids Metals like sodium, potassium, lithium and calcium react vigorously with dilute HCl and H 2 SO 4 to form their metal salt and hydrogen. Non-metals do not react with dilute acids. They taste sour and react with metals. Non metals have tendency to gain electrons, whereas metals have tendency to lose electrons easily. Required fields are marked *, When a metal react with dilute nitric acid,then hydrogen gas is not evolved.Nitric acid is a strong oxidising agent.As soon as hydrogen gas is formed in reaction between metal and dilute nitric acid,the nitric acid oxidises this hydrogen to water.Nitric acid itself is reduced to nitrogen oxides such.

Thus displacing hydrogen from dilute acids. $\begingroup$ Only if there is an oxidizing agent present, or electrolysis is used, can copper metal react with hydrochloric acid. Metals have a tendency to lose electrons and hence they supply electrons, i.e., they are electron donors. Metals below hydrogen in the reactivity series (copper, silver, gold and platinum) will not react with dilute acid. It depends on exactly what acid, and the concentration of that acid. 2Na+2HCl——>2NaCl + hydrogen (react violently), Mg(s) + + 2 HCl (aq) —–> MgCl2 (aq) + H2 (g), Al(s) + 6 HCl (aq) —-> AlCl3 (aq) + 3 H2 (g), Zn(s) + 2 HCl (aq) —-> ZnCl2  (aq) + H2 (g), Fe (s) + 2 HCl (aq) —-> FeCl2  (aq) + H2 (g).
