Answer 2

Answer :

1. Apple - Malic Acid
2. Curd - Lactic Acid
3. Vinegar - Acetic Acid
4. Lemon - Citric Acid
5. Orange - Citric Acid
6. Bee sting - Formic Acid
7. Tamarind - Tartaric Acid

Explanation :

• Malic acid, which accounts for up to 90% of total organic acids in cultivated apples, is a major determinant of fruit acidity .Citric acid is present in mature apple fruits as well; however, its concentration in cultivated apple is very low to undetectable.
• Formic acid is the acid found in honey bee stings. Formic acid gets its name from the Latin word for ant, 'formica.' It is a simple carboxylic acid that is the first member of the carboxylic family. Formic acid is the common name for methanoic acid, a carboxylic acid. HCOOH is the chemical formula for formic acid.
• Tartaric acid is an organic acid found in a variety of vegetables and fruits, including bananas, grapes, and citrus fruits and tamarinds. Its purpose is to produce carbon dioxide.
• Citric acid is a chemical compound with the formula HOC(CH2CO2H)2. It is a colourless organic acid that is weak. It is naturally found in citrus fruits. It is an intermediate in the citric acid cycle, which occurs in all aerobic organisms' metabolism.
• The presence of lactic acid bacteria and the milk protein casein results in the formation of curd. Lactic acid, also known as milk acid, is an organic acid with the chemical formula C3H6O3.
• Acetic acid is a byproduct of fermentation that gives vinegar its distinctive aroma. Vinegar contains approximately 4-6 percent acetic acid in water. More concentrated solutions are available in laboratories, and glacial acetic acid is pure acetic acid containing only traces of water.
