Curd and other sour substances contains acids which can react with the metals of brass and copper vessels to form toxic or poisonous metal compounds which can cause food poisoning and damage our health.

Nitrogen is an inert gas and does not easily react with these substances whereas oxygen reacts with food substances and makes them rancid. Thus, bags used in packing food items are flushed with nitrogen gas to remove oxygen inside the pack. When oxygen is not present inside the pack, rancidity of oiRead more
Nitrogen is an inert gas and does not easily react with these substances whereas oxygen reacts with food substances and makes them rancid. Thus, bags used in packing food items are flushed with nitrogen gas to remove oxygen inside the pack. When oxygen is not present inside the pack, rancidity of oil and fat containing food items is avoided.
A reaction which has an equal number of atoms of all the elements on both sides of the chemical equation is called a balanced chemical equation. As per the law of conservation of mass, mass can neither be created nor destroyed. Hence, in a chemical reaction, the total mass of reactants should be equRead more
A reaction which has an equal number of atoms of all the elements on both sides of the chemical equation is called a balanced chemical equation.
As per the law of conservation of mass, mass can neither be created nor destroyed. Hence, in a chemical reaction, the total mass of reactants should be equal to the total mass of the products. Thus, the total number of atoms of each element should be equal on both sides of a chemical equation.
Magnesium is an extremely reactive metal. In the presence of oxygen, it forms a layer of magnesium oxide on its surface. This layer is quite stable and doesn’t allow further reaction of magnesium with oxygen. Thus, it is necessary to clean magnesium, rubber so that the underlying metal can be availaRead more
Magnesium is an extremely reactive metal. In the presence of oxygen, it forms a layer of magnesium oxide on its surface. This layer is quite stable and doesn’t allow further reaction of magnesium with oxygen. Thus, it is necessary to clean magnesium, rubber so that the underlying metal can be available for reaction.
Why should curd and sour substances not be kept in brass and copper vessels?
Curd and other sour substances contains acids which can react with the metals of brass and copper vessels to form toxic or poisonous metal compounds which can cause food poisoning and damage our health.
