What pigment is least soluble?
Prussian blue is one of the least soluble pigments, meaning it has low solubility in water and other solvents.
Why nitrogen give blue colour with sodium fusion test?
When nitrogen is present in a sodium fusion test, it forms sodium azide (NaN3), which upon heating decomposes into sodium, nitrogen gas, and atomic nitrogen. The atomic nitrogen emits blue light when it reacts with the oxygen in the air, giving the characteristic blue color to the flame during the sodium fusion test.
A solid that forms out of a solution?
The solid that forms out of a solution is called a precipitate. It is formed when the solubility limit of a substance in a solution is exceeded, causing it to separate out as a solid. This process is known as precipitation.

To recover the precipitate.

When was Prussian Blue created?
Prussian Blue was created in 2003.
When did Prussian Blue end?

Why is ferric ferrocyanide prussian blue in lassaignes test?
In Lassaigne's test, when ferric ion reacts with sodium ferrocyanide, it forms a complex called ferric ferrocyanide or Prussian blue, which appears as a blue precipitate. This reaction is specific and sensitive for the detection of the presence of the cyanide ion in a sample.

How can I make Prussian blue?

What is the reason for prussian blue color in a nitrogen test?
Prussian blue forms in the nitrogen test as a result of the reaction between dissolved nitrates and a reagent containing sulfanilamide and napthylethylenediamine dihydrochloride. The formation of Prussian blue indicates the presence of nitrates in the sample being tested.
