Question

A green powder was placed into a beaker of water.After it was stirred the water looked cloudy and lumps of powder could still be found.Has a solution been formed?Explain your answer?

Answer 1

Answer:

The green powder is FeSO4. When it is put into water,as it soluble in water,it dissolves slowly,and a solution of FeSO4 (aq) is prepared.

Answer 2

Ferrous Sulphate

Explanation:

• The green colored powder is of ferrous sulfate
• It is also known as green vitriol
• When it is dissolved and stirred in water, ferrous sulfates from the hydrated metal complex$[Fe(H_2O)_6]_2{^+}$
• This complex is almost colorless and paramagnetic in nature
• Hence, the ferrous sulfate solution is formed

If we heat this iron(II) sulfate will firstly lose its water of hydration and the original green powdery crystals will be changed to white-colored anhydrous solid.
