What happens when solid naphthalene is added to water?

Explanation. Naphthalene is a nonpolar compound. Thus, it is insoluble in highly polar solvents like water. Non-polar solutes do not dissolve in polar solvents like water because they cannot compete with the strong attraction that the polar solvent molecules have for each other.

Does naphthalene dissolve in water?

These chemicals have some of the toxic properties of naphthalene. Some naphthalene will dissolve in water in rivers, lakes, or wells. Naphthalene in water is destroyed by bacteria or evaporates into the air.

Does naphthalene mix with water?

naphthalene năf´thəlēn˝ [key], colorless, crystalline, solid aromatic hydrocarbon with a pungent odor. It melts at 80°C, boils at 218°C, and sublimes upon heating. It is insoluble in water, somewhat soluble in ethanol, soluble in benzene, and very soluble in ether, chloroform, or carbon disulfide.

Can we put naphthalene balls in water?

conclusion Naphthalene was most likely the primary ingredient in all the mothballs purchased for the study. Naphthalene is poorly soluble in water, and 'camphor water' is unlikely to cause harm.

Is naphthalene soluble in cold water?

Explanation: Naphthalene is a nonpolar compound. Thus, it is insoluble in highly polar solvents like water.

How many naphthalene balls cause death?

Is naphthalene a solid or liquid?

Physical / Chemical Properties:

Naphthalene is a white crystalline or colorless to brown solid. Naphthalene has a distinct aromatic odor.

What type of solid is naphthalene?

It is the simplest polycyclic aromatic hydrocarbon, and is a white crystalline solid with a characteristic odor that is detectable at concentrations as low as 0.08 ppm by mass. As an aromatic hydrocarbon, naphthalene's structure consists of a fused pair of benzene rings.

How does naphthalene get in water?

Naphthalene enters the environment when factories produce it, when accidental spills occur, when moth repellents vaporize, or when wood or tobacco burn. At hazardous waste sites and landfills, naphthalene can dissolve in water, attach to soil, and leach into underground drinking water.

Is naphthalene safe to drink?

If swallowed, naphthalene may cause liver and kidney damage and also may cause methemoglobinemia, i.e., bluish discoloration of skin, convulsions and death, severe digestive tract irritation with abdominal pain, nausea, vomiting, diarrhea, and anemia and other blood abnormalities (Source).

What happens when solid naphthalene is heated?

Assuming solid naphthalene is heated. Naphthalene is heated till it reaches its melting point just as the solid begins to melt, it will stay at that temperature until all the molecules in it have absorbed enough kinetic energy to break the bonds keeping it in solid state.

What is naphthalene in chemistry?

naphthalene, the simplest of the fused or condensed ring hydrocarbon compounds composed of two benzene rings sharing two adjacent carbon atoms; chemical formula, C₁₀H₈.

What is sublimation of naphthalene?

Naphthalene is a solid that sublimes at standard atmospheric temperature with the sublimation point at around 80 °C or 176 °F. At low temperature, its vapour pressure is high enough, 1 mmHg at 53 °C, to make the solid form of naphthalene evaporate into gas.

Why naphthalene is non polar?

Whereas in case of naphthalene C - H atoms show an electronegativity difference of 0.4, thus this is treated as slightly polar bond. But concerning the structure of naphtalene (two benzene rings), it is a very stable molecule and won't dissolve easily in water - thus it behaves mostly unpolar.

Why naphthalene dissolves in benzene not in water?

Explanation: Naphthalene is insoluble in water because it is non-polar. This means that it cannot participate in dipole-dipole interactions or hydrogen bonding.

Which is not soluble in water?

Hydrogen (H2) is not soluble in water this is because hydrogen is a non-polar molecule whereas water is a polar molecule. There is a principle that 'like dissolves like' since hydrogen and water are two different types of substances, hence H2 is not soluble in water.

What are mouth balls?

Mothballs are small balls of chemical pesticide and deodorant, sometimes used when storing clothing and other materials susceptible to damage from mold or moth larvae (especially clothes moths like Tineola bisselliella).

What will happen if I eat naphthalene balls?

If swallowed, naphthalene can damage red blood cells, causing kidney damage and many other problems. It can affect how blood carries oxygen to the heart, brain, and other organs. It can also cause nausea, vomiting, abdominal pain, seizures and coma.

Why does my water smell like moth balls?

Napthalene is derived from coal tar, a material that was once used as a standard coating for the lining of water mains installed across the United States until the early 1970s. The coating is safe under normal water conditions.

Is naphthalene poisonous to humans?

Acute (short- term) exposure of humans to naphthalene by inhalation, ingestion, and dermal contact is associated with hemolytic anemia, damage to the liver, and neurological damage.

What is the common name of naphthalene?

Naphthalene is also known as napthene, naphthalin, camphor tar, and white tar.

How do you test for naphthalene?

Place a few crystals of the mothball product in a glass tube or other small container: Add a few drops of chloroform (spectrograde) and a small amount of aluminum chloride anhydrous powder. Naphthalene produces an intense blue color immediately.

Should we keep naphthalene balls in toilets?

(Pack of 500g) Naphthalene Balls can be used for cloth store, pantry, wash basin,lizard,scented fagrance, rats, bathroom, toilets, cockroaches, wardrobe, rooms, scented smell,Insects as Insecticide, disinfectant, Moth Repellent.

Is naphthalene acidic or basic?

The three components of the mixture will react differently to sodium bicarbonate and sodium hydroxide because each of the bases' conjugate acids has a different pKa. The pKa's of benzoic acid and 2-naphthol are 4.17 and 9.5, respectively, while naphthalene is a neutral compound.

Is naphthalene a crystalline solid?

Naphthalene – Crystalline solid. Benzoic acid – Crystalline solid. Teflon – Amorphous solid.

Is naphthalene saturated or unsaturated?

Camphor and naphthalene unsaturated and alcohol is saturated. Naphthalene =unsaturated.
