VR Tour For Std. 10 Ch. 2. Acids, Bases and Salts

What's Included in Virtual tour of this chapter

Acids are the substances that give hydrogen ions in aqua solution. And Bases are the substances that give OH minus ions in aqua solution. Acid and bases are dissolved in water solution, acid gives H+ ions whereas base gives OH– ions. The reaction of metallic oxides with acids. When acid in the base is mixed, resulting in water and salt because acid and base neutralize each other. Crystals of salt are actually dry because the water present in them doesn’t behave like water but gives it a crystalline structure.

Virtual tour 1 Acid and Bases in Laboratory

Virtual tour 1: Acid and Bases in Laboratory

Now we are going to understand how to recognize acid-base by the experiment of litmus papers. Litmus papers are basic indicators that indicate whether the solution or substance is acidic or basic. The acid converts blue litmus paper to red and the base converts red litmus paper to blue.

Virtual tour 2 How do acid and bases react with metals

Virtual tour 2: How do acid and bases react with metals?

In this virtual tour, we will understand the reaction of acid and bases with metals. We will perform an experiment with dilute sulphuric acid in a test tube and also zinc granules and will understand the reaction of acid and base with zinc metal.

Virtual tour 3 How do metal carbonates and metal hydrogen carbonates react with acids

Virtual tour 3: How do metal carbonates and metal hydrogen carbonates react with acids?

This virtual tour will show the reaction of metal carbonates and metal hydrogen carbonates with acids. When an acid reacts with a metal hydrogen carbonate, it releases carbon dioxide gas. In this virtual tour, we will understand that when an acid reacts with a metal carbonate or metal hydrogen carbonate, it produces carbon dioxide gas.

Virtual tour 4 What do all acids and all bases have in common

Virtual tour 4: What do all acids and all bases have in common?

When acid and bases are dissolved in water solution, acid gives H+ ions whereas base gives OH– ions. So both acid and bases are electrolytes that conduct electricity. Hydrogen ions are responsible for the electric current and responsible for acidic properties. So, these acids contain ions to conduct electricity.

Virtual tour 5 What Happens to an Acid or a Base in a Water Solution

Virtual tour 5: What Happens to an Acid or a Base in a Water Solution?

In this virtual tour, we will understand what happens to acid and base in a water solution. We will take a Sulphuric acid test tube and bring it near a test tube that consists of sodium chloride. When hydrogen chloride comes in contact with water, it produces a hydrogen ion, which causes the change of color of litmus paper. When sodium chloride reacts with concentrated sulfuric acid, hydrochloric acid is produced.

Virtual tour 6 Are the crystals of salts really dry

Virtual tour 6: Are the crystals of salts really dry?

Crystals of salt are actually dry because the water present in them doesn’t behave like water but gives it a crystalline structure. When we moisten the crystals with water, we will find that the blue color of the crystals appeared. We will understand that the blue color of cuso4 is because of water elimination.

Virtual tour 7 Reaction of metal oxides with acids

Virtual tour 7: Reaction of metallic oxides with acids

Metallic oxides react with acids to give salts and water. We will understand the reaction of copper oxide with dilute hydrochloric acid. After the reaction takes place the color of the solution becomes blue-green due to the formation of copper (II) chloride and the copper oxide dissolves. This proves that metallic oxides are basic oxides.

Virtual tour 8 Is this an exothermic or endothermic process

Virtual tour 8: Is this an exothermic or endothermic process?

An endothermic process is any process that requires or absorbs energy from its surroundings. An exothermic reaction is a chemical reaction that releases energy through light or heat. It is the opposite of an endothermic reaction. Usually in the form of heat.

Virtual tour 9 How do acids and bases react with each other

Virtual tour 9: How do acids and bases react with each other?

When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water. The compound formed by the cation of the base and the anion of the acid is called a salt.
