Characteristics of Inorganic Chemical Compounds

Vocabulary flashcards covering the characteristics, states, colors, and behaviors of common inorganic chemical compounds.

$$H_2$$

Colorless, odorless gas that burns with a characteristic pop.

$$O_2$$

Colorless, odorless gas that supports combustion.

$$Cl_2$$

Yellow-green gas with a characteristic odor.

$$Br_2$$

Brown liquid with a characteristic odor.

$$I_2$$

Dark crystals that form purple vapors upon sublimation; after dissolving in $H_2O$ it forms a yellow solution, and in chloroform a purple solution.

$$CO_2$$

Colorless, non-flammable gas.

$$CO$$

Colorless, non-flammable gas.

$Al(OH)_3$, $Ca(OH)_2$, $Mg(OH)_2$

White precipitates.

$$AgOH$$

Unstable, dark brown precipitate that decomposes to $Ag_2O$ (dark precipitate).

$$Fe(OH)_2$$

Green, gelatinous precipitate.

$$Fe(OH)_3$$

Orange, gelatinous precipitate.

$H_2SiO_3$, $H_4SiO_4$

White, gelatinous precipitates.

$$BaSO_4$$

White precipitate.

$$AgCl$$

White precipitate that darkens under the influence of light ($2AgCl \rightarrow 2Ag + Cl_2$).

Colorless gas that turns brown in contact with air.

$$NO_2$$

Brown gas with a characteristic odor.
