Although very difficult to work with, tungsten can be cut with a hacksaw, forged, or spun. Commercially, tungsten is obtained via the reduction of tungsten oxide with hydrogen or carbon. Due to its hardness, tungsten has the highest boiling point and highest tensile strength of all metals. Although the metal shows resistance to corrosion, it can oxidize iMore

Sulfuric acid

CAS No: 7664-93-9

Formula: H2O4S

Categories: Inorganic Chemistry > Inorganic Acid

Sulfuric acid is a very strong, diprotic acid. It is hygroscopic and readily absorbs moisture from air. It is a powerful oxidizing agent and reacts with many metals at high temperatures. Concentrated H2SO4 is also a strong dehydrating agent. Addition of water to concentrated sulfuric acid is a very exothermic reaction and can lead to explosions.
C(s) + H2SO4(aq) → 2SO2(g)+2H2O(l)
Fe(s) + H2SO4(aq) → H2(g) + FeSO4(aq)
Sn(s) + 2 H2SO4(aq) → SnSO4(aq) + 2 H2O(l) + SO2(g)

Cesium

CAS No: 7440-46-2

Formula: Cs

Categories: Inorganic Chemistry > Elementary Substance

Cesium is silvery gold, soft ductile metal. It is the most electropositive and alkaline element. Cesium, gallium, and mercury are the only three metals that are liquid at or around room temperature. Cesium reacts explosively with cold water, and reacts with ice at temperatures above -116℃. Cesium hydroxide is a strong base and attacks glass and reacts with halogens to form a fluoride, chloride, bromide, and iodide. Cesium metal oxidizes rapidly when exposed to air and can form the dangerous supMore

Platinum

CAS No: 7440-06-4

Formula: Pt

Categories: Inorganic Chemistry > Elementary Substance

Platinum is a silvery to whitish-gray metal, that is malleable and ductile (Weast, 1988; Krebs, 2006). It is estimated that the average platinum concentration in the earth’s lithosphere ranges from 0.001 to 0.005 mg/kg (WHO, 1991). It has a vapor pressure of approximately 0mmHg (NIOSH, 2005). Platinum, depending on mining location, is found in sperrylite, cooperite, braggite, and copper–nickel sulfide ores, and in alloys with other members of the platinum group elements (PGE; iridium, osmium, pMore

Ruthenium

CAS No: 7440-18-8

Formula: Ru

Categories: Inorganic Chemistry > Elementary Substance

Ruthenium is a chemical element with symbol Ru and atomic number 44. Ruthenium is a rare transition metal belonging to the platinum group of the periodic table. More

Frequently Asked Questions

Why is inorganic chemistry important in industry?

Inorganic chemistry is fundamental to multiple industries. It supports the development of catalysts, pigments, coatings, fertilizers, batteries, ceramics, and pharmaceutical intermediates. Understanding inorganic reactions and properties allows industries to improve product performance, increase efficiency, and develop innovative solutions for modern technology and sustainable processes.

What is the difference between inorganic and organic chemistry?

The main difference lies in the type of compounds studied:

Organic chemistry focuses on carbon-containing compounds, including hydrocarbons and their derivatives, studying their structure, reactivity, synthesis, and applications.

Inorganic chemistry focuses on compounds not primarily based on carbon-hydrogen bonds, including metals, salts, minerals, and nonmetal compounds, exploring their properties, reactions, and industrial applications.

Both branches overlap in areas like organometallics and coordination chemistry, but their core scope differs.

What substances are inorganic?

Inorganic substances are those that generally lack C-H bonds. Examples include salts such as sodium chloride and potassium nitrate; metals like iron, copper, and aluminum; minerals and oxides such as quartz, diamond, and titanium dioxide; and other compounds including inorganic phosphates, sulfates, and nitrates. Inorganic compounds are widely used in chemical manufacturing, catalysis, materials, electronics, water treatment, and environmental applications.

What is inorganic chemistry?

Inorganic chemistry is the branch of chemistry that studies compounds and elements that generally do not contain carbon-hydrogen (C-H) bonds. It focuses on the properties, structures, reactions, and applications of inorganic substances, which include metals, salts, minerals, oxides, acids, bases, and coordination compounds. Inorganic chemistry plays a key role in industries such as materials science, catalysis, energy storage, pharmaceuticals, and environmental chemistry.
