Hydroxides are chemical compounds composed of one or more hydroxide ions (OH-) bound to a metal ion. They are classified as bases and are typically found in solid form, although some may exist in solution.
Hydroxides play vital roles in various industrial processes, environmental chemistry, and biological systems due to their diverse properties and applications.
10 Examples of Hydroxides
- Sodium hydroxide (NaOH) – Commonly known as caustic soda, used in soap making, water treatment, and as a cleaning agent.
- Calcium hydroxide (Ca(OH)2) – Also called slaked lime, used in construction, agriculture, and as a food additive.
- Magnesium hydroxide (Mg(OH)2) – Known for its use in antacids and laxatives due to its ability to neutralize stomach acid.
- Potassium hydroxide (KOH) – Used in the manufacture of detergents, fertilizers, and batteries.
- Aluminum hydroxide (Al(OH)3) – Employed as an antacid and in the production of aluminum metal and various chemicals.
- Iron(II) hydroxide (Fe(OH)2) – Found in nature as the mineral goethite and used in water purification and as a pigment.
- Copper(II) hydroxide (Cu(OH)2) – Utilized as a fungicide and in the production of batteries and catalysts.
- Zinc hydroxide (Zn(OH)2) – Important in the pharmaceutical industry and as a precursor to zinc oxide.
- Barium hydroxide (Ba(OH)2) – Used in analytical chemistry and as a dehydrating agent.
- Strontium hydroxide (Sr(OH)2) – Employed in pyrotechnics and as a stabilizer in plastic production.
Conclusion
Hydroxides encompass a wide range of compounds crucial to numerous industries and applications. From the household to industrial settings, these substances serve as bases, reactants, and catalysts, showcasing their versatility and significance in chemistry.
