Question

Tomato is a natural source of which acid?
A) Acetic acid
B) Citric acid
C) Tartaric acid
D) Oxalic

Answer 1

Tomatoes are the edible berries of the plant Solanum Lycopersicum, also known as the tomato plant. The species is thought to have originated in western South and Central America. The Nahuatl word tomato gave rise to the Spanish word tomate, which gave rise to the English word tomato.

Complete answer:
Any hydrogen-containing substance capable of donating a proton (hydrogen ion) to another substance is referred to as an acid. A base is a molecule or ion that can accept hydrogen ions from acids. The sour taste of acidic substances is usually used to identify them.

Tomatoes are an excellent natural source of oxalic acid. All three of the remaining acids play a role in protecting your health and sustaining energy. Tomatoes only have a "moderate" amount of oxalic acid (approx. 50 mg per 100 g). The amount of Vitamin C in tomatoes decreases as they ripen, while the number of oxalic acid increases.

Oxalic acid acts as a reducing agent for metal oxides, removing tarnish, rust, and ink stains. Commercially, it is used as a laundry rinse, a wood-bleaching agent, and a calcium remover. Some paints and varnishes can be removed with oxalic acid. It is also used as a mordant in textile dyeing and the production of ink. Thus tomato is a natural source of oxalic acid

Thus, the correct answer is option ‘D’ i.e, oxalic acid.

Note: All tea leaf varieties contained moderately high levels of oxalic acid. Oxalic acid was found in significant amounts in almond, brinjal, carrot, coconut, colocasia, gingelly seeds (black and white), kamrak, Laronda, tamarind (pulp), wood apple, and yam.
