Uses of Bases
Bases have diverse uses across various industries and applications due to their chemical properties. Some common uses of bases include:
Household Cleaning
- Alkalis, or bases are commonly used in many household cleaning agents. Both sodium hydroxide and potassium hydroxide tend to have strong alkaline properties to dissolve the grease and other organic matter residues
- Example: Sodium hydroxide is used in drain and oven cleaners to dissolve grease and organic matter.
Medicinal Uses
- Bases are used in many medical applications ranging from acid neutralization as an antacid, and as an antiseptic as well. Magnesium hydroxide and calcium carbonate, neutralize excess gastro acid and alleviate the symptoms of indigestion and heartburn.
- Moreover, disinfection and sanitization can be effected with the use of a base known as caustic soda or chlorine bleach; it is effective in treating wounds, etc.
- Example: Magnesium hydroxide is used as an antacid to neutralize stomach acid.
Wastewater Treatment
- Bases are used in water treatment processes to adjust pH, remove heavy metals, and neutralize acidic wastewater. For example, lime (calcium hydroxide) is commonly used in water treatment plants to soften water and precipitate impurities.
- Example: Sodium hydroxide is used to neutralize acidic pollutants in wastewater treatment.
Food Processing
- Bases are used in food production for various purposes, such as controlling pH, leavening, and preservation. It changes food textures, and enhance food flavor.
- Bases like sodium bicarbonate (baking soda) is used as a leavening agent in baking to produce carbon dioxide gas, which helps dough rise.
- Example: Sodium hydroxide is used to alkalize cocoa beans in chocolate production.
Textile Dyeing and Finishing
- Bases act as the main components of chemical compounds in the textile industry. They are used as tints in dyeing processes while they also aid in improving dye uptake and finishing off fabric properties.
- Sodium carbonate (soda ash) and sodium hydroxide are the most preferred alkaline agents in textile dyeing because they are capable of fixing and stabilizing dyes on fabrics that could otherwise be washed off.
- Example: Sodium hydroxide is used in textile dyeing to fix dyes on fabrics.
Electroplating
- Bases are used in electroplating processes to prepare metal surfaces for plating by removing oxides and contaminants.
- Example: sodium hydroxide is used as a de-greasing agent in metal preparation before electroplating.
