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.                                                                  




                                                          

                      You can see in image definition, of chromophore and Auxochrome.When chromophore  and Auxochrome comes together, they shift absorption of wavelength from low to longer. you can see in image benzene  is the  chromophore , (OH ,OCH3) 
are Auxochromes. anisole and phenol are two different combinations of Auxochrome  and chromophore. They shift absorption of wavelength  from 
UV to visible. 
 





   We can just see visible region through our eyes. 


  We can get different artificial colours by managing amount of Auxochrome  and chromophore in dyes.

Let's  see through  the example.









There is red colour shirt in the image. We can see the red colour of that shirt because,The dyes( contain chromophore and Auxochrome) Which are used in that process almost able to absorbe all colours  without red .that reflected  red colour when incident  on our eyes, it ,suddenly creates image in our mind.                                 
By the same way, we can see other colours.

How do you prepare 1M or 1N hcl ?

±  How to make 1 Molar or 1 normal hcl In case of HCL molarity & Normality is same Because- Because HCL = H+ + CL-  HCL contain only one H+ ion means Basicity Of HCL is = n = 1  Normality = molarity  × n   n =  [Basicity of HCL ]  N= M×1   So  N = M (That is why in case of HCL Normality & molarity is same ) Now let's see how to make 1 N or 1M  HCL from 37% concentrated HCL This calculation varies with concentration of HCL. Because density varies with concentration of HCL . Now we are having density 1.18 for 37% concentrated HCL.  If you are going to use less concentrated HCL then first find out density of it then put that value in below formula instead of 1.18. HCL is liquid, so at first we need to convert HCL molecular weight (gm) into volume (ml) let's use formula density = mass / volume volume = mass of HCL   / density                           ...

Why Birds don't get Electrocuted on Power Cables?

        E lectricity is the flow of electrons through conductors . It always takes the easiest route, i.e., electricity always flows through a path of least resistance .      electricity flows are made of copper . Copper offers least resistance and is a very good conductor of electricity. However, the bird's body offers greater resistance and is not a good conductor as copper. Hence, electricity ignores the bird and flows through the cables and birds don't get electrocuted.      B esides this, electricity flows from its highest potential to its lowest potential . Now, the power cables usually run at different potentials. If bird's feet are on the same power cable, then they are at same potential. Thus, the bird doesn't get electrocuted. However, when the bird touches two cables with different potentials at the same time, then electricity will flow through the bird to go to the other cable with lower potential and the bird will get elec...
