Question

Name one natural source of each of the following acids:
A) Citric acid
B) Oxalic acid
C) Lactic acid
D) Tartaric acid

Answer 1

Hint:To solve this question, we must first understand what is Natural acid and what are its sources. Then we need to assess the sources in order to answer every query and then only we can conclude the correct answer.

Complete step by step answer:
Before we move forward with the solution of this given question, let us first understand some basic concepts Natural acid:
Organic Acid which is also known as Natural acid is an organic compound with acidic properties. The most common organic acids are the carboxylic acids, whose acidity is associated with their carboxyl group \[-COOH.\]
Organic acids are weak acids and do not dissociate completely in water, whereas the strong mineral acids do. Lower molecular mass organic acids such as formic and lactic acids are miscible in water, but higher molecular mass organic acids, such as benzoic acid, are insoluble in molecular form. Organic acids are infrequently used alone as curing agents. The reaction mechanism is the key to the utility of the acid anhydrides.
So the sources are mentioned below:
Citric acid: Lemon
Oxalic acid: Tomatoes
Lactic acid: Sour milk or curd
Tartaric acid: Tamarind

Note:Biological systems create many more complex organic acids that contain hydroxyl or carboxyl groups. Human blood and urine contain these plus organic acid degradation products of amino acids, neurotransmitters, and intestinal bacterial action on food components. Organic acids added to feeds should be protected to avoid their dissociation in the crop and in the intestine and reach far into the gastrointestinal tract, where the bulk of the bacteria population is located.
