acids and base and their properties

 

Acids:--

               An acid is a molecule or ion that is capable of donating a proton that is hydrogen ion (H+ ) or capable of formation of a covalent bond with an electron pair.

Acid:--

In the water solution, any substances whose tastes are sour and whose dissolve in water to release H+ ions and reacts with bases to form salts and promotes certain chemical reactions and also change the colour of certain indicators. This is known as acid.

 

Properties of acids:--

Acids is sour in taste

Acids react with base to form salt

Acid reacts with metal to release hydrogen ions H+

The pH value is less than 7

Acid converts blue litmus paper to red litmus paper

Acid have tendency to corrode the metal surfaces

 

 

Bases:--

            Bases are the substances which dissociates solution to form hydroxide ion OH-  and which can donates electrons and accept protons.

 

Properties of bases :--

Bases are bitter in taste

It has pH value is greater than 7

The bases reacts with acids to form salts

Salts are slippery in touch

Salts has ability to accept protons.

The colour of the litmus paper changes from red litmus paper to blue litmus paper.

They conduct electricity when dissolve in water

A soluble base is called an alkali if it contains and release OH- ions.

A base is a substance that can accept hydrogen cations that is H+ which is known as protons.

Sign convention for spherical lenses

Image
  Sign convention for spherical lenses Sign convention of spherical lens is similar to the sign convention of the spherical mirrors.         Object is placed on the left of the lens. It means to say that light must passes through the lens from left to light. All measurements of distance are taken from the optical centre of the lens. The focal length of a convex lens is positive. And the focal length of the concave lens is negative. All distance measured above the principal axis are positive. All distance measured below the principal axis are negative. All the distance measured in the direction of incident rays are positive. All the distance measured in the direction opposite to that of the incident rays are negative.     Lens formula and magnification   Lens formula provides the relationship between object distance (u) ,   image distance (v) and the focal length (f). lens formula is applicable of both concave lens and convex lens. The image generated by th

The refractive index

Image
                      The refractive index The refractive index:-- When a ray of light travels from one transparent medium into another medium, the change of direction takes place in a given pair of media is called as refractive index. the refractive index can be linked with the important physical quantity, the relative speed of propagation of light in different media.   It means speed of light propagates with different speeds in different media. Speed of light is faster in vacuum with speed   of 3 * 10 8   meters/second. but in the air, the speed of light is 2.98   * 10 8 meters/second. It means speed of light in air   is compared less as compared with speed of light in the vacuum. And the speed of light in glass and water is less than the speed of light in vacuum. The refractive index determine the path of light is bent or refracted, when entering any medium.                          The refractive index is expressed as the   degree of the change of direction   of the ligh

Electromagnetic induction, fleming's right hand rule

Image
                         Electromagnetic induction   When a current carrying conductor is placed in a magnetic field in such a manner that the direction of the current is perpendicular to the magnetic field , a force is experienced. This force causes the conductor to move.     Now suppose that a conductor is moving inside the magnetic field or magnetic field is changing around a fixed conductor. This was first studied by English physicist Michael Faraday. And faraday made an important discovery that how a moving magnet can be used to generate electric currents.     To illustrate , how a moving magnet can be used to generate electric currents.   Let us take a coil of wire AB with a large number of turns. And the ends of the coil is connected to the galvanometer       And take a bar magnet. And move its north pole towards the end B of the coil. Then we observed that there is a deflection in the needles of the Galvanometer. This indicates that there is a pr
