Answer:
A mineral acid or inorganic acid is any acid derived from an inorganic compound that dissociates to produce hydrogen ions (H+) in water. Mineral acids are highly soluble in water but tend to be insoluble in organic solvents. The inorganic acids are corrosive.
Mineral acids are also known as inorganic acids. The main difference between mineral acid and organic acid is that mineral acids are inorganic compounds composed of different chemical element combinations whereas organic acids are organic compounds essentially composed of carbon and hydrogen atoms.
Mineral Acids: Sulphuric acid (H2SO4), Nitric acid(HNO3) Organic Acids: Citric acid(C6H8O7), Acetic acid(CH3COOH) Alkalis: Potassium hydroxide(KOH), Sodium hydroxide(NaOH)

Mineral Acid: A mineral acid is a water-soluble acid derived from inorganic minerals by chemical reaction. Example: Nitric Acid (HNO3), and Sulphuric Acid (H2SO4). Organic Acid: The acids which are present in plant minerals and animals are called organic acids. Example: Acetic Acid (CH3COOH) and Lactic Acid (C3H6O3).
Litmus paper and turmiric are the two substances that can be used as indicators.
In chemistry, neutralization or neutralisation (see spelling differences) is a chemical reaction in which acid and a base react quantitatively with each other. In a reaction in water, neutralization results in there being no excess of hydrogen or hydroxide ions present in the solution.
Properties of Salt
Crystals or white crystalline powder.
Transparent and colourless in crystalline form – rather like ice.
Crystallises in the isometric system, usually in the form of cubes.
Soluble in water (35.6g/100g at 0°C and 39.2g/100g at 100°).
Potassium sulphate and sodium chloride are neutral salts, sodium carbonate is basic salt and ammonium chloride is acidic salt.
