Hey there! We receieved your request. Acids is defined as the one which produces hydrogen ions in water. Acids are classified as Organic Acids and 2 Ncert Class Chemistry 10th Chapter Course Mineral Acids. Acids which are derived from plants and animals, they are known as Organic Acids.
For ExampleCitric Acid from fruit. Mineral acids are inorganic acids such 2 Ncert Chapter Class Course 10th Chemistry as Sulphuric Acid. They are dangerous to be used, so need more precautions. Acids are also classified as Strong Acids or Weak Acids. Strong acid is an acid, that completely dissociates into ions in aqueous solutions.
Weak acid is the one Class 10th Ncert Chemistry Chapter 2 Course which does not dissociate completely into ions in aqueous solutions. For ExampleAcetic Acid. Acids Class 10th Ncert Chemistry Chapter 2 Course can also be as Dilute Acid and Concentrated Acids. The one which has low concentration of acids in aqueous solution, they are known as Dilute Acids whereas the one which has high concentration of acids in aqueous solution, are known as Concentrated Acids.
It is advisable to add acid to water and not vice versa because large amount of heat is released if water is added to acid. This released heat is large enough to cause harm.
Acids can also be classified based on number of hydrogen ions. Monoprotic acid is the one which 10th Course Class Chapter 2 Chemistry Ncert gives one boat slips for sale st joseph mi yang of hydrogen ions per mole of acid, such as HCl.
Diprotic Acid is the one which produces two mole of hydrogen ions per mole of acid. For ExampleH 2 SO Class 10th Ncert Chemistry Chapter 2 Course 4. Bases are the one which produces hydroxide ions in aqueous solutions. Bases which are water soluble they are known as Alkalis. Bases are classified as Strong Base and Weak Base.
Strong base is the one which dissociates completely into its Class 10th Ncert Chemistry Chapter 2 Course Ncert Solutions For Class 10th Science Chapter 3 Note ions in aqueous solution. For ExampleNaOH. Weak base is the one which does not dissociate completely into its ions in aqueous solutions.
Bases are also classified as Dilute Base and Concentrated Base. The solution which has low concentration of base in aqueous solution is defined as Dilute Base whereas the one which has high Class 10th Ncert Chemistry Chapter 2 Course concentration of base in aqueous solution is known as Concentrated Base. Strength of an acid or base can be determined using a pH scale. It is a Class 10th Ncert Chemistry Chapter 2 Course scale to measure the hydrogen ion concentration in a solution. Stomach has a pH of about 2 due to presence of hydrochloric acid in it.
It is needed for the activation of pepsin protein required for protein digestion. When we eat food boat slips for sale st joseph mi yang sugar, then class 10th ncert chemistry chapter 2 course bacteria present in our mouth break down the Class 10th Ncert Chemistry Chapter 2 Course sugar to form acids.
This acid lowers the pH in the mouth. Tooth decay Class 10th Ncert Chemistry Chapter 2 Course starts when the pH of acid formed in the mouth falls below 5. This is because then the acid becomes strong enough to attack the enamel of our teeth and corrode it. This sets in tooth decay. The best way to prevent tooth decay is to clean the mouth thoroughly after eating food. Many animals and plants protect themselves from enemies by injecting painful and irritating acids Class 10th Ncert Chemistry Chapter 2 Course Class 10th Ncert Chemistry Chapter 2 Course and bases into their skin.
When honey bee stings a person, it injects an acidic liquid into the skin. Rubbing with mild base like baking soda solution on the stung area of the skin gives relief. When a wasp stings, it injects an alkaline liquid into the skin. Then rubbing with a mild acid like vinegar on the stung area of the skin gives relief.
Soil pH and plant growth: Most of the plants grow best when the pH of the soil is close to 7. If the soil is too acidic or basic, the plants grow badly or do not grow at all.
The soil pH is also affected by the use of chemical fertilisers in the field. Chemicals can be added to soil to adjust its pH and make it suitable for growing plants. If the soil is too acidic then it is treated with materials like quicklime or slaked lime. If the soil is too alkaline then alkalinity can be reduced by adding decaying organic matter.
When acid and base neutralize, salts are formed. Strong acid and strong base combines to form neutral salt. Formation of Neutral Salt. Strong acid and weak base combine to form acidic salt. For ExampleHydrochloric Class 10th Ncert Chemistry Chapter 2 Course Class 10th Ncert Chemistry Chapter 2 Course Acid and ammonium hydroxide combine to form ammonium chloride.
Other examples, sodium hydrogen Class 10th Ncert Chemistry Chapter 2 Course carbonate, sodium hydrogen sulphate. Formation of Acidic Salt. Similarly, weak acid and Class 10th Ncert First Chapter Calculations strong base combine to form basic salt. For ExampleAcetic Acid and sodium hydroxide combine to form sodium acetate. Other examples are calcium carbonate, potassium cyanide.
Formation of Basic Salt. They are the substances that which indicate acidic or basic nature of the 2 10th Course Chapter Ncert Chemistry Class solution using colour change. For Examplelitmus solution, methyl orange, phenolphthalein, methyl red. Acids convert Class Chemistry Ncert Course 2 Chapter 10th blue litmus paper red in colour. Bases turn red litmus blue. Phenolphthalein remains colourless in presence of acids but turn pink in presence of bases.
It is mined from underground deposit like coal. Raw material for making large number of Class 10th Ncert Chemistry Chapter 2 Course Ncert 10th Chemistry 2 Class Course Chapter useful chemicals in industry. Passing electricity through concentrated solution of NaCl called ' brine '. It is called chloro-alkali process because products formed are chlorine Chloro and NaOH alkali.
The CO 2 produced during the process gets trapped in wet dough and bubbles out slowly to make cake 'rise' so that it becomes soft and spongy. Washing Soda Na class 10th ncert chemistry chapter 2 course CO 3. The Cl 2 produced by action of dilute acid acts as bleaching agent. Boat slips Class 10th Ncert Chemistry Chapter 2 Course for sale st joseph mi yang bleaching cotton and linen in textile industry, for bleaching wood pulp in paper factories, for bleaching washed clothes in laundry. Plaster of Paris P.
P CaSO 4. Has remarkable property of setting into a hard Chapter Course 10th Class Chemistry 2 Ncert 10th Chapter Chemistry Class Course Ncert 2 mass on wetting with water, as gypsum is formed. CaSO 4. Hence, P. P should be stored in moisture-proof container as moisture can cause slow boat slips for sale st joseph mi yang of P. P by hydrating it. Used Class 10th Ncert Chemistry Chapter 2 Course in hospital for setting fractured bones in the right position to ensure correct healing. Making toys, decorative materials, cheap ornaments, and casts of statues.
Making smooth surfaces, Class 10th Ncert Chemistry Chapter 2 Course such as For making ornamental designs on ceilings of houses and other buildings.
