How to make 1N and 1M H2SO4 ?

Now let's see how to make 1 N and 1M  H2SO4 from 98% concentrated H2SO4 . This calculation varies with concentration of H2SO4. Because density varies with concentration of H2SO4 . Now we are having density 1.84 for 98% concentrated H2SO4.  If you are going to use less concentrated H2SO4 then first find out density of it then put that value in below formula instead of 1.84 H2SO4 is liquid, so at first we need to convert H2SO4 molecular weight (gm) into volume (ml) let's use formula density = mass / volume volume = mass of HCl  / density                             98.08 / 1.84 V = 53.30 ml Here we are making 1M and 1N  H2SO4 from 98% concentrated H2SO4. If you are going to use less concentrated H2SO4 then use that percentage value in below formula rather than 98%. Let's use formula  1M H2SO4 (98%) =  53.30 ml [ V ]                100%  ...

WHAT ARE ARTIFICIAL COLOURS ?

                 In twenty first century our whole life is associated  with artificial things. And that  whole   things has artificial colour. like clothes, bags, toys, Polymers, bottles each and everything.    Let's  see how to create artificial  colours.  All industry's use dyes or colorful  pigment to create artificial  colour. And  that dyes contain chromophore and Auxochrome,they are responsible  for appearance  of artificial colours.     You must know, what are chromophore and Auxochrome.                                                                                                          ...

HOW CAN WE SEE THROUGH OUR EYES ?

         we can see the different  things like tree and surrounding objects etc. Through  our eyes, because  structure  of human eye make us able to see the things.          Let' see the structure  of human eyes.     This is  the structure  of our eye. Cornea is the transparent part of our eyes. When light radiation incident on the cornea,  then they pass through  the cornea and incident on lens. This lens  are called  convex  lens. This  lens concentrate  all light which passed  through the cornea. Then concentrated  light incident  on main part of our eye called retina   and produce colourfull  image. NOW  YOU  WILL  ASK  ME , HOW CAN  WE  SEE  THE COLOURS ? This is very interesting  point. It's  all depends  on the radiation which is reflected  from objects. you must ...
