(a) … Cast Iron should react with both concentrated and dilute Sulfuric acid to produce an aqueous solution of Iron (II) Sulfate. A, B, C and D are respectively: reacts with dilute acids to produce hydrogen gas but magnesium is an exception. Learn more about such concept. Which statements about metal X are correct? Sulfuric acid and reactions with it Sulfuric acid and reactions with it Chemical properties of sulfuric acid. Iron metal dissolves readily in dilute sulphuric acid in the absence of oxygen forming Fe(II) ions and H 2. Place about 5cm depth of the acid in each of the five test tubes; Place a small piece of each of the three metals above. Which of the following reacts with cold water vigorously? Iron sulfide - FeS; Sulfuric acid - When the above-mentioned reactants interacts, the following chemical reaction occurs: Due to the double displacement reaction, the reaction between iron sulfide and dilute sulfuric acid leads to the formation of Ferrous sulfate and hydrogen sulfide gas. Does Iron react differently with dilute and concentrated hydrochloric acid? A imparts a deep golden yellow colour to a smokeless flame. Metals generally react with dilute acids to produce hydrogen gas. Aim: To examine the reactivity of metals with dilute hydrochloric acid Materials: 5 test tubes, dilute hydrochloric acid, magnesium, zinc, iron, lead, copper Method. Concentrated nitric acid, HNO 3, reacts on the surface of iron and passivates the surface. Some metals reacts vigorously with dilute sulfuric acid or hydrochloric acid for example, potassium, sodium, lithium and calcium. Could someone tell me: 1. Sulfate salts and chloride salts are formed when metals react with dilute sulfuric acid and hydrochloric acid. For example, magnesium reacts rapidly with dilute hydrochloric acid: These elements include lithium, potassium, calcium, sodium, magnesium, aluminum, zinc, iron and lead. 1) This one involves using gaseous hydrogen chloride which reacts with solid iron to form solid iron(II) chloride and hydrogen gas (anhydrous means without water). 23 Metal X lies between zinc and iron in the reactivity series. H2SO4 will produce FeSO4 (aq) which is what your aiming for, you might as well use dilute since you will not have to deal with the Sulfur Dioxide gas being produced in the reaction. M g + 2 H C l → M g C l 2 + H 2 D reacts with this solution of C and produces the same gas B on warming. (a) magnesium (b) aluminium (c) iron (d) copper. Share Tweet ... With cold con­cen­trat­ed sul­fu­ric acid, such met­als as iron and alu­minum do not re­act, as they are cov­ered with an ox­ide film. Fe(s) + 2HCL(g) = FeCl2(s) + H2(g) 2) Here we have solid iron being dissolved in a solution of hydrochloric acid (which is basically the hydrogen chloride gas dissolved in water). Magnesium being an active metal liberates dihydrogen gas as it is allowed to react with dilute H C l.Thus all the given metals react with dilute acids. 3 The metal can be obtained from its oxide by heating strongly with charcoal. D can also produce gas B on reaction with dilute H 2 S O 4 . A. I know that with dilute hydrochloric acid Iron (II) chloride is formed. 1 It reacts with steam to produce hydrogen gas. Metals to the right of hydrogen in the electrochemical series, such as copper, silver and gold, do not react. Metals to the left of hydrogen in the electrochemical series react with hydrochloric acid. 2 It does not react with steam but will produce hydrogen with dilute acid. 7. and dil. 8. Most of the metals such as A l, C u, F e etc. Which one of the following metals does not react with dilute hydrochloric acid? Iron reacts with oxygen, O 2, forming Fe(II) and Fe(III) oxides. B. I read on the internet that with concentrated hydrochloric acid Iron reacts to form Iron (III) Chloride. Since both conc. Reaction of iron with air. When a substance A reacts with water, it produces a combustible gas B and a solution of substance C in water.
