Vocabulary-style flashcards covering the physical properties, ores, symbols, and chemical reactions of Iron and Lead as detailed in the lecture notes.

Ferrum

The Latin word from which the chemical symbol for Iron ($Fe$) is derived.

Iron Electronic Configuration

$$[Ar]\,4s^2\,3d^6$$

Hematite

An oxide ore of iron with the chemical formula $Fe_2O_3$.

Limonite

An oxide ore of iron with the chemical formula $2Fe_2O_3 \cdot 3H_2O$.

Magnetite

An oxide ore of iron with the chemical formula $Fe_3O_4$.

Iron Pyrite

A sulphide ore of iron with the chemical formula $FeS_2$.

Copper Pyrite

A sulphide ore of iron with the chemical formula $CuFeS_2$.

Sidrite

A carbonate ore of iron with the chemical formula $FeCO_3$.

Rust

The product formed by the slow reaction of iron with moist air, with the formula $2Fe_2O_3 \cdot xH_2O$.

Ferrosoferric oxide

A compound ($Fe_3O_4$) formed when iron burns in oxygen or reacts with steam.

Iron Carbonyl

A compound ($Fe(CO)_5$) formed when iron combines with carbon monoxide at $120^\circ\text{C}$.

Passivity of iron

The formation of a layer of ferroso ferric oxide ($Fe_3O_4$) on the surface of iron when treated with pure and highly concentrated nitric acid, which prevents further reaction.

Matlockite

A chloride ore of lead with the chemical formula $PbCl_2PbO$.

Litharage

Lead oxide ($PbO$) formed by heating lead in the presence of air at $300^\circ\text{C}$.

Red lead

A compound ($Pb_3O_4$) formed by heating lead oxide ($PbO$) at $450^\circ\text{C}$.

Plumbo solvency

The solvent action of water on lead which forms slightly soluble lead hydroxide ($Pb(OH)_2$), causing toxicity in lead water pipes.

Sodium plumbate

A compound with the formula $Na_2PbO_2$ formed when lead reacts with an alkali like $NaOH$.
