Class 10 Science Ncert Solutions for Chapter 2 Acids, Bases and Salts
An acid is defined as a substance whose water solution tastes sour, turns blue litmus red and neutralizes bases. … Salt is a neutral substance whose aqueous solution does not affect litmus. According to Faraday: acids, bases, and salts are termed as electrolytes
Uses of Acids and Bases
Uses of Acids. Vinegar, a diluted solution of acetic acid, has various household applications. It is primarily used as a food preservative. …
Uses of Bases. The manufacturing of soap and paper involves the use of sodium hydroxide. NaOH is also used in the manufacture of rayon.
Acids, bases and salts affect chemistry as well as our day to day life. They can be easily identified by their taste; that is acids taste sour and bases taste bitter and salts itself have salty taste.
When weak acid reacts with a strong base, then basic salt is formed.
|Acid are those that can donate electrons||Bases are those that can accept protons|
|The pH values of acids are basically less than 7||The pH values of bases are basically more than 7.|
|Acids turn blue litmus red.||The Base turns red litmus blue.|
Acids and bases are important in living things because most enzymes can do their job only at a certain level of acidity. Cells secrete acids and bases to maintain the proper pH for enzymes to work. For example, every time you digest food, acids and bases are at work in your digestive system.
In every-day life, acids and bases play a role in everything from digestion of the foods you eat to the function of the medicine you take and even the cleaning products you use. Without acids and bases, many of the products in your home today would not have much use.
In general, acids are sour/tart, feel like water, may sting when touched, react strongly with metals, conduct electricity since they ionize in solutions, and turn blue litmus paper red. Bases are bitter, slippery and smooth, do not react with metals usually, conduct electricity, and turn red litmus paper blue.
Acids are the substances which are sour in taste. Bases are the substances which are bitter in taste. … And bases are the substances which gives OH-ion when combine with water. Acids are the substances whose pH is in between 0-7 and bases are the s whose pH is in between 7-14.
In industry, acids and bases are used in various reactions. Sulphuric acid, one of the most important industrial chemicals, is used to manufacture fertilizers for agriculture, to make man-made fibers, paints and dyes, and to purify petroleum products.
Examples of Everyday Bases
Soaps and bath products.
You can find acids and bases in your own home in the form of food and household products.
Citrus Fruits. ••• Oranges and lemons, for instance, contain citric acid, which makes them acidic home products.
The range goes from 0 – 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
Acids taste sour, are corrosive to metals, change litmus (a dye extracted from lichens) red, and become less acidic when mixed with bases. Bases feel slippery, change litmus blue, and become less basic when mixed with acids.
Are Acids or Bases More Dangerous?
The simple answer is that both acids and bases can be dangerous depending on their pH level, or how strong they are. For example, a strong acid would be more dangerous than a weak base, and the other way around.
An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition). A base is a substance that can accept protons or donate a pair of valence electrons to form a bond.
Bases typically produce a more severe injury known as liquefaction necrosis. This involves denaturing of proteins as well as saponification of fats, which does not limit tissue penetration. Hydrofluoric acid is somewhat different from other acids in that it produces liquefaction necrosis.

5 Why is Electricity Conducted Through an Aqueous Solution of Acid?
Ans. When electricity is passed through an aqueous solution of an acid, the H+ ions reach the cathode and each H+ ion picks up one electron from the cathode to form H2 gas. Because of this reaction, an aqueous solution of acid conducts electricity.
Acids are good conductor of electricity when they are taken in aqueous solution. When an acid is dissolved in water, It lose hydrogen ions and loses lots of anions as well. … The stronger the acid, the more hydrogen ions in solution (and more anions), the better the conductor.
