Why is the copper sulfate solution blue in color?

Absorption of Light As it happens, the difference in energy for the copper sulfate complex is equivalent to the difference in energy for photons of light in the red-orange region of the spectrum. Since reddish light is absorbed while blue light is transmitted, the copper sulfate appears blue.

What is copper sulfate used for in everyday life?

For over 200 years, copper sulfate has been used for various purposes, including tanning leather, bleaching wood pulp, dyeing cotton and woolen cloth, coagulating milk products, and cleaning copper utensils.

Why are copper salts blue?

In compounds copper sulphate, the blue colour is due to the light energy being used to promote or excite electrons that are in the atom of the copper when it’s combined with other things such as the sulphate or carbonate ions and so on. It’s the waters there that are interacting with the copper ions.

Why does copper give off a blue green flame when burned?

When you burned the skewer tip coated with copper sulfate, you should have seen that the flame gained blue-green traces. This is because when the metal copper is burned, it makes bluish-green light. If an atom’s electrons lose energy, they drop down to a lower energy level, and the lost energy can be released as light.

Is copper fungicide safe for humans?

It is one of many pesticides approved under the USDA National Organic Program. A number of studies show that it is highly toxic to humans, animals, beneficial insects and the environment.

Can copper sulfate be poured down the drain?

The copper sulfate doesn’t reach the majority of the roots, basically making it useless. OK, so cleaning your own drains with copper sulfate is a bad idea.
