Also to know is, what happens to naphthalene when heated?

When heated at 80 °C, napthalene rapidly sublimes directly from a solid into a gas, eventually leaving nothing remaining in the crucible. On cool surfaces, the gaseous naphthalene will re-solidify to form needle-like crystals.

Beside above, why naphthalene must be stirred continuously? In the cooling of naphthalene, the boiling tube containing the liquid naphthalene is cooled inside a conical flask. This is to ensure that an even cooling process is carried out. Stirring the naphthalene continuously also ensures even heating or cooling.

People also ask, why is water bath used instead of direct heating?

It is also used to enable certain chemical reactions to occur at high temperature. Water bath is a preferred heat source for heating flammable chemicals instead of an open flame to prevent ignition.

What are the side effects of naphthalene?

Some of the symptoms that occur with hemolytic anemia are fatigue, lack of appetite, restlessness, and a pale appearance to your skin. Exposure to a large amount of naphthalene, such as by eating mothballs, may cause nausea, vomiting, diarrhea, blood in the urine, and a yellow color to the skin.
