Is naphthalene denser than water?
A white crystalline volatile solid with a strong coal-tar odor. The solid is denser than water and insoluble in water.
Is naphthalene less dense than water?
Napthalene is denser than water but doesn’t mix with water. It can be set on fire, but it’s hard to ignite. Its melting point is 80.2 degrees C, and its boiling point is 217.9 degrees C. It has a molecular weight of 128.174 g/mol.
Why is naphthalene insoluble in water?
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.
What is NaOH not soluble in?
It is highly soluble in water, with a lower solubility in polar solvents such as ethanol and methanol. NaOH is insoluble in ether and other non-polar solvents.
What is the density of naphthalene?
1.14 g/cm³Naphthalene / Density
How does naphthalene dissolve?
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.
What can dissolve naphthalene?
It is insoluble in water, somewhat soluble in ethanol, soluble in benzene, and very soluble in ether, chloroform, or carbon disulfide. Naphthalene is obtained from coal tar, a byproduct of the coking of coal.
What solvent dissolves naphthalene?
What makes NaOH soluble in water?
When sodium hydroxide (NaOH) dissolves in water, it separates into positively – charged sodium ions (cations) and negatively – charged hydroxide ions (anions). These ions move around in the water, free and independent of each other, though cations tend to be surrounded more closely by anions and vice versa.
What does NaOH react with?
Sodium hydroxide reacts with strong acids (hydrochloric, sulfuric or nitric), water, and moisture to rapidly release heat. Sodium hydroxide reacts with metals (aluminum, lead, tin or zinc) to form flammable and explosive hydrogen gas.
In which solvent was naphthalene soluble?
Does naphthalene dissolve in organic solvents?
Naphthalene is a nonpolar compound. Thus, it is insoluble in highly polar solvents like water.
