Sulphuric

Uses of sulphuric acid Sulphuric acid is a very useful, referred as universal chemical because it is a commonly used chemical in the world and is used in a lot of manufacturing industries, for example, car battery, manufacturing fertilisers, refining crude oil, making phosphoric acid etc. This chemical is also known as one of the most important industrial chemical. This acid has helped us in many ways, making things easier for us. What is sulphuric acid? Sulphuric acid is a chemical compound

acid in your stomach helps digest food which in large quantities causes indigestion to occur. If indigestion does occur, it is necessary to neutralize it with a base. Nature also produces acids that are toxic to humans one that is known as sulphuric acid. Sulphuric acid is extremely harmful if you are directly exposed to it. However it is very useful in real life. For example, in car batteries, used in plant fertilizers. On the contrary, It is very dangerous to the environment. There are many acids

acid batteries occurs at the cathode, as shown above. Lead (from lead dioxide) is reduced at the cathode by protons in the sulphuric acid: PbO2(s) + 4H+(aq) + 2e- → Pb2+(aq) + 2H2O(l) In order to galvanise iron or steel, sulphuric acid is used to remove oxides. An oxidant is a reactant that oxidises or removes electrons from other

Introduction: Aim: To investigate the effect of sulphuric acid concentration (mol L-1) on the time taken (seconds) for magnesium pieces to dissolve in it. Independent variable: The concentration of sulphuric acid. (mol L-1) Dependent variable: Time taken (seconds) for the magnesium to dissolve. Hypothesis: If the concentration of sulphuric acid (mol L-1) is increased, then the time taken for the magnesium to dissolve should decrease. Controlled variables: • The size of the beaker used to dissolve

Sulphuric Acid Production Should Not Be Banned Background Information Acids and bases are chemical compounds with certain properties, and are classified according to several different definitions. There are clear distinctions between the two types of compounds, and although they share some similarities in their physical and chemical properties, their uses and applications vary greatly. Acids can be described as having a sour taste, producing hydronium ions in water, forming a salt and water when

Everything that happens through what we do and still doing creates a chain reaction of the ecosystems and because of this, it makes a huge affect on the earth we live in. Mining is an industry that is becoming bigger and bigger, day-by-day and it has that large effect on the earth, but the downside to this is that there is a demand for different rocks that’s also becoming larger and larger, thus causing the need for larger mines and equipment. Another problem that could come with mining would be

Altering the Amount of Heat Produced When Magnesium Reacts with Sulphuric Acid When energy in the form of heat is given out of a reaction it is an exothermic reaction. Exothermic reactions usually need activation energy, the energy to break the bonds in the chemicals and to start the reaction. Once the bonds are broken new stronger bonds are formed. In an exothermic reaction energy in the form so heat is given out to the surrounding when the products are formed. Therefore

Given that the most common mineral in limestone is calcium carbonate, describe how limestone objects are corroded by the sulfuric acid in polluted air. What chemical reaction is involved here? Sulfuric acid formation in the air emanates from pollutants released in the atmosphere especially, from manufacturing industries (Hewayde, Nehdi, Allouche & Nakhla, 2007). When the gas, (sulfur dioxide) is released into the air, it combines with oxygen to form another gas (sulfur trioxide, SO3), which reacts

never know. Soaps and detergents are one of those things. Acids and bases are everywhere but, there are two specific types: Sulphuric Acid and Sodium Hydroxide which we use on a regular day bases. An acid classifies a wide range of materials including Sulphuric acid and bases Sodium Hydroxide. When manufacturing soaps they use Sodium Hydroxide, and detergents use Sulphuric Acid. But these two can be very poisonous, and there are many symptoms that may happen, some even severe. The title shows how

experiment, sulphuric acid, H2SO4 and potassium permanganate, KMnO4 is added into glucose with different concentration and the time taken for the purple pink colour of potassium permanganate solution to change to colourless is recorded. This is because glucose donates electrons to the permanganate
