physical properties of nitric acid

Electrons in different metals can have different energies. If two of these metals are placed in a conducting liquid (electrolyte) a difference in electrical potential is set up between them. A pair of different metals arranged in this way is an electrochemical cell. It converts chemical energy to e..

Colour - Pure nitric acid is a colourless liquid. But commercial nitric acid may be yellowish brown, due to the presence of dissolved nitrogen dioxid..

Pure nitric acid is a colorless fuming liquid with a pungent odor. Impure acid or pure acid on standing develops yellow color due to the presence of dissolved oxides of nitrogen (mainly NO 2 ). It is completely soluble in water and forms a constant boili..

When a bar magnet is suspended freely, it always comes to rest in a north-south direction. This property is used in the construction of a mariner's compass. ..

A magnet attracts magnetic substances like iron, steel etc. This property is used to separate iron from a mixture, to remove iron filings from the eye et..

Properties of Matter - A solid has certain characteristics: According to modern theory, the molecules of a solid are fixed in relation to each other. They vibrate in place, but do not wander around. This accounts for the fact that a solid keeps its own shape. Solids are usually crystallin..

According to modern theory, the molecules of a solid are fixed in relation to each other. They vibrate in place, but do not wander around. This accounts for the fact that a solid keeps its own shape. Solids are usually crystalline. A solid is a crystalline substance in which the molecules, at..

On observing waves, it may be observed that they travel with a definite speed through a uniform medium. If we watch a particular spot, we find that the waves pass that spot at regular intervals of time. The following definitions help in describing wave motio..

When a zero vector is added to another vector , the result is the vector only. Similarly, when a zero vector is subtracted from a vector , the result is the vector . ..
