Two alkalis and two acid used in the labratory
1 acid is HCl
1 alkali is NaOH.
In a laboratory setting, there are several common alkalis (bases) and acids that are used for various purposes. Here are two examples of each:
1. Alkalis (bases):
a. Sodium hydroxide (NaOH): This is a highly caustic and corrosive substance commonly used as a strong base in laboratories. It is often used in titrations, neutralizations, and as a cleaning agent. To find sodium hydroxide in a laboratory, you can check the chemical storage area or contact the lab manager or chemical supplier.
b. Ammonium hydroxide (NH4OH): Also known as ammonia solution, this is a weak base commonly used in analytical chemistry and for cleaning purposes. It is relatively less caustic compared to sodium hydroxide. Ammonium hydroxide can usually be found in a chemical storage area in the laboratory or chemical supply cabinets.
2. Acids:
a. Hydrochloric acid (HCl): This is a strong, corrosive acid commonly used in chemistry labs. It is often used for pH adjustments, titrations, and as a cleaning agent. Hydrochloric acid is typically stored in a dedicated acid storage area in a laboratory. It should be handled with care due to its corrosive nature and used in a fume hood if necessary.
b. Sulfuric acid (H2SO4): This is another strong acid commonly used in laboratories for a variety of purposes, including pH adjustments, synthesis reactions, and as a dehydrating agent. Sulfuric acid is usually stored in the acid cabinet or acid storage area, and it should be handled with great caution due to its highly corrosive nature.
When working with alkalis or acids in the laboratory, it's essential to familiarize yourself with their properties, safety precautions, and proper handling procedures before using them. Always follow the laboratory's safety guidelines and wear appropriate personal protective equipment (PPE) when working with these chemicals.
