What makes copper sulphate blue

It tastes like dishwater and looks very pale from dilution as well. I'll be back after I make a fresh pot of strong, deep black, coffee :- Regards,. This is because of the Jahn-Teller effect, because the electrons crowd each other. Hi Lorial The amount of light that passes through a solution the colour you see depend upon the concentration of the solution.

The more dilute the solution by adding water the more light in this case blue that passes and the colour is lighter. This can be used to measure the concentration. I suggest that you do a search on "Beer's Law" and "Absorption spectroscopy" for a more detailed explanation.

Dear sirs, I have problem in copper blue colour in aluminium chloride please give me method to removal of blue color from aluminium chloride. SOOO I am busy doing my homework and the first question they asked me was what the original colour for copper chloride solution and I said blue, sooo then for question 2 they asked explain the colour of the solution, sooo what must I write down for the answer?

I really need help ASAP. Hi Chasity. In one sense, all of the explanations here are fine because the actual reason that copper chloride is blue is the same for you as it is for anyone else in the world whether they be kindergarteners or post-docs.

But what may be different for you, depending on your grade, is to what depth you must explain the blue color. Good luck. Thanks Prabhkara. That may be the case -- and if it is, then Chasity can talk about d-block metal ions per Robert Smith's posting, or electrons bumping to higher energy levels per Samuel Pryor's posting, etc.

But one of the world's greatest physicists and teachers, Richard Feynman, frequently instructed us that you need a starting point what you already know and an ending point a depth beyond which you will not try to go for all such questions or you never get anywhere :- I think but obviously don't know , that the chief curiosity for many students in this matter is that they know copper is orange colored, so they initially expect that copper should dissolve as an orange colored solution.

The color change tells them that something different and more interesting than dilution is going on. Thanks Ted. That great teacher-scientist Richard Feynman has made the point pretty clear. That is how science progresses. Progress stops the moment questions cease.

So it sucks air into it, which, as anybody knows who has looked at the sky, is blue :- A2. Ted Mooney , P. Striving to live Aloha finishing. The forum is a one-room schoolhouse with some readers 3rd-graders, and some post-docs, so it's sometimes hard to know what depth students require and can understand :- Regards, Ted Mooney , P.

Indeed it is often the starting raw material for the production of many of the other copper salts. It is estimated that approximately three-quarters of this is used in agriculture, principally as a fungicide, but also for treating copper-deficient soils. Copper sulphate is a very versatile chemical with as extensive a range of uses in industry as it has in agriculture.

Its principal employment is in agriculture, and, up to a generation or so ago, about its only uses in industry were as a mordant for dyeing and for electroplating. Today it is being employed in many industrial processes:. Indeed, today there is hardly an industry which does not have some small use for copper sulphate. In the table below, some of the many uses of copper sulphate are listed.
