tamarind and curd taste sour. Why?​

Answer 1

Answer:

because they are basic in nature

Answer 2

Acids have a sour taste and can change the colour of litmus paper from blue to red.

Explanation:

• Basically, they contain very weak acids, lime, orange juice, tamarind, and other sour foods taste sour.
• The second group of acids are Lewis acids, which create a covalent bond with an electron pair. Lewis viewed this as a generalisation of Bronsted's notion, in which an acid is a chemical species that receives electron pairs either overtly or by releasing protons (H+) into the solution and then accepting electron pairs. However, hydrogen chloride, acetic acid, and the vast majority of Bronsted-Lowry acids are not Lewis acids and do not create a covalent bond with an electron pair.
• Because the majority of acids used in everyday life are aqueous solutions that may be dissolved in water, the Arrhenius and Bronsted-Lowry definitions are the most important.
• Acids have a sour taste and can generate aqueous solutions, turn blue litmus red, and react with bases and certain metals to form salts (like calcium).
