Sulfuric acid (H 2 SO 4) is a strong acid. It is an odorless, clear to dark brown, oily liquid that is corrosive. Sulfuric acid has many industrial purposes and is produced in greater quantities than any other chemical worldwide. In metal mining, sulfuric acid is used to leach copper oxide minerals. In one process, a solution of sulfuric acid laden

The reaction is: Zinc + Sulfuric acid → Zinc sulfate + Hydrogen. Zn (s) + H 2 SO 4 (aq) → ZnSO 4 (aq) + H 2 (g) In test tube 2, copper is the catalyst for the reaction, and the reaction should be faster than in test tube 1, but may not be as fast as test tube 3. In test tube 3, zinc displaces copper from the copper sulfate solution and the ...
As gases, sulfur dioxide (SO 2) and sulfur trioxide (SO 3) gases are produced. Sulfuric acid is manufactured by lead chamber or contact process in industrial scale. Sulfur or metal sulfide or hyrogen sulfide gas …
Sulphur, air or oxygen and water are the raw materials for the manufacture of sulphuric acid. (a) Sulphur is burnt in air to produce sulphur dioxide. (b) Sulphur dioxide can also be produced by burning metal sulphides such as zinc sulphide and lead sulphide. (c) The sulphur dioxide is then mixed with excess air and dried.
Published by Statista Research Department, Feb 1, 2024. In 2023, China produced around 19 million metric tons of sulfur, making it by far the world's leading sulfur producer. Sulfur is one of the ...
As a result of the acid-carbonate reaction, carbon dioxide is produced and the lime water turns milky. In this reaction setup, lime water, a dilute calcium hydroxide ((Ca(OH)_2)) solution, is poured into one of the test tubes and sealed with a stopper. A small amount of hydrochloric acid is carefully poured into the remaining test tube.
Dilute sulfuric acid, 0.5 M (IRRITANT), 25 cm 3; ... B1.38 How to determine the name of the salt produced in the following acid-base reactions: acid + base → salt + water (for example, HCl + NaOH → NaCl + H₂O) Healthcare science. B1 Core science concepts. Acids/bases and chemical change.
Definitions of Acids and Bases. In Chapter 4.6, we defined acids as substances that dissolve in water to produce H + ions, whereas bases were defined as substances that dissolve in water to produce OH − ions. In fact, this is only one possible set of definitions. Although the general properties of acids and bases have been known for more than a …
A typical sulfuric acid plant operating on sulfur as the main raw material consists of the following main sections: 1. Sulfur feeding section. 2. Waste heat recovery …
Sulfuric acid is produced from sulfur, oxygen, and water via the contact process. In the first step, sulfur is burned to produce sulfur dioxide. (1) S + O 2 → SO 2 (g) This product is then oxidized to sulfur trioxide using oxygen in the presence of a vanadium(V) oxide catalyst. (2) 2 SO 2 + O 2 (g) → 2 SO 3 (g) (in presence of V 2 O 5)
In essence, the health effects of sulfuric acid are related to the direct irritation of the respiratory tract…. The AEGL-1 values are based on respiratory irritation observed in many human volunteer studies at concentrations higher than 0.2 mg/m3…. The AEGL-2 values are based on the absence of severe or disabling acute effects in the large number of …
Sulfuric acid is used in the manufacture of paints, detergents and fertilisers. The contact process demonstrates a reversible reaction used in the production of sulfuric acid.
When sulfuric acid comes into contact with the skin, it can cause third-degree burns. If you are exposed to sulfuric acid, you should wash your hands with soap and lukewarm water for at least 30 minutes. In some cases, the acid may be strong enough to penetrate your clothing, necessitating removal of your clothing and water flush.
Because the reaction you mention works in the opposite way. It's. NaCl +H2SO4 HCl(g) +Na2SO4 2 + () +. – Mithoron. Nov 9, 2023 at 16:00. 5. Most sulphate salts are produced from sulfuric acid, so converting them back is hardly an efficient process. – matt_black. Nov 9, 2023 at 17:07.
Sulfuric acid is prepared industrially by the reaction of water with sulfur trioxide ( see sulfur oxide ), which in turn is made by chemical combination of sulfur dioxide and oxygen either by the contact process or the chamber process.

Sulfuric acid, the most abundantly produced chemical in the United States, is manufactured by the contact process. Most (about 70%) of the sulfuric acid produced in the world is used in the fertilizer industry. Sulfuric acid can act as a strong acid, a dehydrating agent, and an oxidizing agent. Its applications use these properties.
Therefore, the mass of sulfuric acid produced by the complete reaction of 48.51 grams of sulfur trioxide is 49.92 grams. This reaction is significant because it demonstrates how sulfur trioxide in the atmosphere reacts with moisture to form sulfuric acid drops, which can contribute to acid rain. To learn more about acid rain:
The half-equations for the electrolysis of water (electrolyte of acidified with dilute sulphuric acid). (a) The negative cathode electrode reaction for the electrolysis of water. The negative cathode electrode reaction is a reduction (electron gain). The hydrogen ions (H+) are attracted to the negative cathode and are discharged as hydrogen gas.
