How to Form Rainbow colour in chemistry

                                 R  Rainbow Colour Reaction 



Here Is the List of the reactions that are used to form rainbow colour in chemistry.That are Easily available in a School chemistry lab.
                                                   Image result for rainbow colour in test tube

For Violet Colour - Use Potassium Permanganate And Cold Water
                         4KMnO4+ 2H2O → 4MnO2 + 3O2 + 4KOH
For Prussian Blue - Use Potassium Hexacyanoferrate and FeCl3
                   3K4[Fe(CN)6] + 4FeCl3 →  12KCl + Fe4[Fe(CN)6]3
For Pink Colour - Use Potassium Permanganate and Hot water
                                ( KMnO4 + Water is heated till gets Pink)
                          4KMnO4+ 2H2O → 4MnO2 + 3O2 + 4KOH
For Green Colour - Use Iron Salt and Sulphuric Acid And Water
                      Fe2+ + H2SO4 + xH2O → FeSO4 + H2O + 2H+
For Yellow Color - Use K2CrO5
                            Dissolve in water
For Orange Color - Use K2Cr2O7
                             Dissolve in Water
For Red color Use Fe(SCN)3-
       take any organic compound containing nitrogen and Sulphur , If it is solid then react it with Na           using fusion tube , and if the organic compound is liquid then remove H2O from it , then put Na         metal in it.
                                              Na   + C + N + S  → NaSCN
                                                        [ From O.C.]
                          3NaSCN  +  FeCl3 → 3NaCl + Fe(SCN)3

How To Remove Proxy Virus [127.0.0.1:8080] 100%[works]

Hi Guys! If you are seeing this blog means you have probably been disgusted by the proxy virus  127.0.0.1:8080  .

Quantitative Estimation [ Theory and Procedure ]

Objectives To prepare a standard solution of sodium carbonate. To determine the strength of a given solution of hydrochloric acid by titrating it against  standard sodium carbonate solution. The Theory What is Titration? One of the important methods in Quantitative Analysis is Volumetric Analysis, a commonly used laboratory technique. It is used to determine the unknown concentration of a sample by measuring its volume. This process is also called titration. In a titration, a solution of unknown concentration is reacted with a solution of known concentration. The solution taken in the burette is called the titrant and the solution taken in the conical flask is called the analyte. What does the end point of a titration mean? The endpoint of a titration is the point at which the reaction between the titrant and the analyte becomes complete. Generally the endpoint of a titration is determined using indicators. What is a standard solution? A solution of known concentrat
