This helps students to gain a better understanding of the chapter's concepts through these easy and comprehensive solutions. Class 10th science chapter 2 is part of unit 1, Chemical Substances - Nature and Behaviours. This chapter portrays acid and base reactions and depicts how acid and base generally cancel out each other. Acid, base and salt class 10 includes topics such as How do Acids and Bases react with each other or metals, Reaction of acid with Hydrogen carbonates and Metallic oxides, Reaction of bases with oxides, etc.

Isotonic solutions are those solutions which have the same osmotic pressure. Also they have same molar concentration. It is die ratio of the normal and observed molar masses of the solute, i. Solutions Class 12 Ncert Solutions Class 10th Chemistry Chapter 3 Course Notes Chemistry Chapter 2 1. RD Sharma Class 12 Solutions. Explanation of every important term related to Acids and Bases. The main points of the chapter 2 is covered through these notes.

Important Questions and Previous years board questions related to Class 10 Science Chapter 2 are given below with answers. The language Class 10th Chemistry Chapter 5 Ncert Solutions Map for notes is kept very simple and easy, so that everyone can understand. Prepare Class 10 Science Chapter 2 using simplified Notes with keywords and explanation. All the definition and equations related to 10th Science Chapter 2 Acids, Bases and Salts are given below.

All mineral acids are strong acids except carbonic acid. For example: sulphuric acid, hydrochloric acid, nitric acid, phosphoric acid. All organic acids i. For example: tartaric acid, oxalic acid, formic acid, acetic acid, etc.

Acid can be diluted by mixing of acid into water. Dilution of acid is an exothermic process. Caution: Always acid is slowly mixed in water to dilute the acid. Never mix water into acid to dilute. Mixing of water into acid can be very dangerous. A base gives bitter taste. A base feels soapy when touched. A base turns red litmus paper blue. Example: Caustic soda sodium hydroxide , washing soda sodium carbonate , potassium hydroxide, slaked line calcium hydroxide , etc.

All metal oxides, metal hydroxides, metal carbonates are base. Chemical properties of base are just opposite to that of acids. When a base is added to acid, both neutralize each other, in such reactions respective salts are formed along with water Oxides, hydroxides, and carbonates of all metals are base.

Example: Calcium is an alkaline earth metal, thus its oxide, calcium oxide quick lime , its hydroxide, which is known as calcium hydroxide slaked lime and its carbonate calcium carbonate lime stone are base. Sodium is an alkali metal, thus sodium oxide, and sodium hydroxide and sodium carbonate are base.

Potassium is an alkali metal thus potassium oxide, potassium hydroxide and potassium carbonate are base. Water soluble base is known as alkalis. Alkali is a basic ionic salt of alkaline metals. Lithium, sodium, potassium, etc. Beryllium, magnesium, calcium etc. Therefore hydroxides of alkali and alkaline earth metals are called alkalis. Example: sodium hydroxide, calcium hydroxide, potassium hydroxide, lithium hydroxide, etc.

Ammonium hydroxide is another important base, although it is the hydroxide of non-metal. Ammonia is a hydride salt of non � metal, but it is a base.
