Though lead is above hydrogen in the activity series, it does not react with dilute hydrochloric acid or dilute sulphuric acid. Metals to the right of hydrogen in the electrochemical series, such as copper, silver and gold, do not react. The products of the reaction are a salt plus hydrogen gas. Figure \(\PageIndex{1}\): (a) Iron powder reacts rapidly with dilute hydrochloric acid and produces bubbles of hydrogen gas because the powder has a large total area: 2Fe(s) + 6HCl(aq) 2FeCl3(aq) + 3H2(g). It is dangerous to put these metals into an acid. The Reaction of Metals with Dilute Acid.. Potassium, sodium, lithium and calcium all react violently with dilute sulfuric acid and dilute hydrochloric acid. When hydrochloric acid reacts with iron, you will notice the reaction because of the bubbling. how many grams of acid are needed to react with 75.0 grams of iron (II) sulfide ore which contains 30.0% inert material? Correct Answer : (D) Copper. This is because Cu is less reactive than Hydrogen. Metals generally react with dilute acids to produce hydrogen gas. Metals to the left of hydrogen in the electrochemical series react with hydrochloric acid. Reactions of metals with acids. The reaction between hydrochloric acid and lead is very slow, producing only a few small bubbles of hydrogen gas. The reaction is similar to the reaction with water, forming the metal salt (either sulfate or chloride) plus H 2(g).. For example. iron (II) sulfide reacts with hydrochloric acid to produce iron (II) chloride and hydrogen sulfide gas? Answer: Pb (lead) is above hydrogen in reactivity series. Iron reacts with hydrochloric acid to produce iron(III) chloride and hydrogen gas.Fe(s) + HCl(aq) -----> FeCl3(aq) + H2(g)The hydrogen gas from the reaction of 2.200 g of iron with an excess of acid is collected ina 10.00 L flask at 25.0°C. (a) … Potassium and sodium are not used for reaction with dilute hydrochloric acid or dilute sulphuric acid in laboratory preparation of hydrogen. (surfaceb) An iron nail reacts more slowly. Potassium and sodium are not used to react with dilute ‘hydrochloric acid or dilute sulphuric acid in the laboratory preparation of hydrogen. 3H2SO4 + 2Al —> Al2(SO4)3 + 3H2 b)Dilute hydrochloric acid reacts with sodium carbonate 7. Dilute sulphuric acid + Aluminium powder —> Aluminum Sulphate + Hydrogen gas. The metal which doesn't react with dilute HCl among the following metals is Copper. please provide the formula … Which one of the following metals does not react with dilute hydrochloric acid? These elements include lithium, potassium, calcium, sodium, magnesium, aluminum, zinc, iron and lead. Though lead is above hydrogen in the activity series, it does not react with dilute hydrochloric acid or dilute sulphuric acid. Which of the following reacts with cold water vigorously? 8. Lead is not used as a protective coating on other metals as it is poisonous. (a) magnesium (b) aluminium (c) iron (d) copper. No, hydrochloric acid does not need air to react with iron. Dilute acids react with relatively reactive metals such as magnesium, aluminium, zinc and iron. Although you should take a look at what Klaus said, copper does in fact react with hydrochloric acid, it just takes a week until all the copper is converted into copper chloride (green) and another week or so until it forms crystals and you can dissolve them in water to form copper chloride again (but depending on the amount of chloride it has, it'll be blue or green).
