GENERAL KNOWLEDGE

Detailed explanation-1: -Acidic compounds are believed to taste sour because of their hydrogen ion concentration, whereas many bases are bitter compounds & are indeed alkaline, but this is because natural bitter compounds often contain amine groups. Amine groups are weak bases. Acids taste sour, and this is because of the pH.

Detailed explanation-2: -Acids are compounds with specific characteristic properties. An acid reacts with metals and carbonates, tastes sour, and turns blue litmus paper to red.

Detailed explanation-3: -What are the properties of acids? When dissolved in water, acids taste acidic, conduct electricity and react with metals to create hydrogen gas. Some indicator compounds can be used to detect acids, such as litmus. Acids turn blue litmus paper into red.

Detailed explanation-4: -Acids taste sour, conduct electricity when dissolved in water, and react with metals to produce hydrogen gas. Certain indicator compounds, such as litmus, can be used to detect acids. Acids turn blue litmus paper red.

Detailed explanation-5: -Acids are sour in taste. Acids furnish hydrogen ions in aqueous solution. Acid reacts with metal to form hydrogen gas. Acid reacts with carbonates and liberates carbon dioxide gas. Blue litmus turns red in acid.
