What is the Chemical composition of black salt?

Answer 1

well i have conducted an experiment on black salt as per my requirements and i found out that it comprised of the following cations and anions:


anions: Na(sodium),NH4,Ni(very little)
cations:S^2-,Cl,CH3COO^-


although the presence of nickel is still a mystery to me as we r taking about edible salt.
but these were my experiment's results.

Answer 2

Black Salt (known as Kala Namak or Sanchalin Hindi) is a special type of Indian volcanic rock salt. It is actually

purple-ish/pinkish grey rather than black and has a very distinctive sulfurous mineral taste, rather like hard boiled

egg yolks.

It is mined from the volcanic regions of Pakistan and India.

Black Salt is used in Indian cuisine as a condiment and adds its distictive flavour to tangy fresh salads called 'chaats',and also in fresh chutneys, snacks, pickles, raitas(yogurt-based salads) and many other savoury Indian items. It is sometimes used to flavour tall summer cool drinks like the famous cumin-scented Jal Jeera.

According to India's classical medical science, Ayurveda, black salt is full of therapeutic benefits. It is rich in iron, and is a cure for flatulence and heartburn.

According to Ayurveda doctors, sea and especially rock salt are the most beneficial forms of salt because unlike ordinary salt, they don't increase the sodium content of blood and are therefore recommended for patients with high blood pressure. It is also a rejuvenator while aiding digestion and improving eyesight.

Answer 3

It is not one chemical formula because it is a mixture of at least 4 compounds, on which I found the following information:

Black salt (or black Indian salt, Hindi: Kala Namak), is a salty and pungent smelling condiment used in India. The condiment is composed largely of sodium chloride with several impurities lending the salt its colour and smell.

Composition:

Kala namak consists primarily of sodium chloride (NaCl) and trace impurities of sodium sulphate (Na2SO4), iron sulphide (FeSO4) and traces of hydrogen sulphide(H2S)

Color&Smell:

Due to impurities in the mineral, it is brownish pink to dark violet translucent stone when whole and when ground into a powder, it is light purple to pink in color.

Sodium chloride provides kala namak with its salty taste, iron sulphide provides its dark violet hue, and all the sulphur compounds give kala namak its slight bitter taste as well as a highly distinctive smell, with hydrogen sulphide being the most prominent contributor to the smell.

Answer 4

"Black salt" is a little ambiguous, but the chemical formula of salt is NaCl. It doesn't take much in the way of impurities to color it. One kind of "black salt" has small quantities of iron (II,III) sulfide (Fe3S4) in it that give it a dark (purple in bulk, pinkish when finely ground) color. Another kind is just ordinary salt with small quantities of activated charcoal (chemical formula C) added to make it appear black.

Answer 5

Kala Namak, black salt, is a type of rock salt used in South Asia. The condiment is composed largely of sodium chloride with several impurities lending the salt its color and smell.

Answer 6

please tell me the chemical composition of black salt and it is formed

Answer 7

Black salt contain sodium chloride (NaCl) and activated charcoal (C); it is a stupid and useless condiment.

Answer 8

This is sodium chloride (NaCl) with some impurities (charcoal, sulfides etc.)

Answer 9

H2Na3ClFeS3O4
