6. What is electroplating?
Answer: Electroplating is the process of plating a metal onto the other by hydrolysis mostly to prevent corrosion of metal or for decorative purposes. The process makes use of an electric current to reduce dissolved metal cations to develop a lean coherent metal coating on the electrode. Electroplating is often applied in the electrical oxidation of anions on a solid substrate like the formation of silver chloride on silver wire to form silver chloride electrodes. It is also majorly applied to modify the surface features of an object (e.g. corrosion protection, lubricity, abrasion). However, the process can also be used to build thickness or make objects by electroforming.
What is meant by ‘One Ampere’?
Answer: One Ampere is the current which when flowing through each of the two parallel uniform long linear conductors placed in free space at a distance of one meter from each other will attract or repel each other with a force of 2 × 10-7 N/m. Check here for more information about Ampere.

8. What is fermentation?
Answer: Fermentation is an anaerobic process in which energy can be released from glucose even if oxygen is not available. Fermentation occurs in yeast cells and bacteria and also in the muscles of animals. It is an anaerobic pathway in which glucose is broken down.
Write the main uses of alcohol (Any two).
Answer: Methanol is a highly versatile chemical, also known as methyl alcohol, commonly used for manufacturing applications and ubiquitous in our daily lives. As an energy carrier, its performance has made it increasingly popular as a fuel for factories and for producing electricity. Meanwhile, ethanol is used as a solvent, in the manufacture of other organic compounds, and as an additive to automobile fuel (a mixture known as gasohol). Ethanol is a major industrial chemical. The intoxicating portion in many alcoholic drinks, such as beer, wine, and distilled spirits, is ethanol. Isopropyl alcohol is used as rubbing alcohol and is present in many items of hand sanitiser. It is also quickly antimicrobial against bacteria, fungi, and viruses, particularly in solutions between 60 and 90 per cent alcohol with 10-40 per cent filtered water.
9. Explain Gravity separation method of Ore.
Answer: The process of removal of the gangue from Ore is known as Concentration or Dressing or Benefaction. There are numerous methods of concentration, and the methods are chosen based on the properties of the ore. Two of these are hydraulic washing and magnetic separation. Hydraulic washing is a type of Gravity separation method of Ore. This method concentrates the ore by passing it through an upward stream of water whereby all the lighter particles of gangue are separated from the heavier metal ore.
What is rusting? Give a chemical formula of rust.
Answer: Rusting of iron refers to the formation of rust, a mixture of iron oxides, on the surface of iron objects or structures. This rust is formed from a redox reaction between oxygen and iron in an environment containing water (such as air containing high levels of moisture). The rusting of iron is characterised by the formation of a layer of a red, flaky substance that easily crumbles into a powder. This phenomenon is a great example of the corrosion of metals, where the surfaces of metals are degraded into more chemically stable oxides. However, the term ‘rusting’ is generally used to refer to the corrosion of objects made of iron or iron-alloys. The chemical formula for rust can be found here.

17. What is soap? Why are detergents better than soap? Explain it.
Answer: A soap is a water-soluble compound which is made via a process called saponification by the reaction between sodium hydroxide or potassium hydroxide with vegetable or animal oil (fats). Detergents are better than soaps as they are ammonium or sulphonate salts of long-chain carboxylic acids. The charged ends of these will not precipitate with calcium and magnesium present in hard water. On the other hand, soaps will form a precipitate with calcium and magnesium ions present in the hard water. Read more about soap and detergents here.

What is Haemodialysis? What is the reason for Haemodialysis? Explain.
Answer: In hemodialysis, blood is pumped out of the body, filtered through a machine and returned to the body through the tubes that connect the patient to the machine. In this method, the patient’s blood is passed through the dialysis machine, where it is purified and returned to the patient’s body. Dialysis is used for people with a critical kidney disorder – grave kidney damage, previously severe renal failure. It is required when the kidney loses 90% of its efficiency and has a glomerular filtration rate of less than 15. This treatment may continue for months or years since most kidney failures are irreversible. When the kidneys fail, it results in many complications and to compensate for this situation, a technology called dialysis has been developed. It uses a machine filter called a dialyser or artificial kidney to remove excess water and salt, to balance other electrolytes in the body and remove waste products of metabolism. Unlike peritoneal dialysis, hemodialysis is not to be carried out every day.
