In a laboratory, there are various acids commonly used for different purposes. Here are some of the commonly encountered acids:
Hydrochloric acid (HCl): This is a strong acid used for general laboratory purposes such as pH adjustment, acid cleaning, and chemical synthesis.
Sulfuric acid (H2SO4): Another strong acid, sulfuric acid is used in a wide range of applications, including acidification, dehydration, and as a reagent in various chemical reactions.
Nitric acid (HNO3): Nitric acid is commonly used in laboratories for metal etching, metal cleaning, and in the production of explosives, dyes, and fertilizers.
Acetic acid (CH3COOH): Also known as vinegar in its diluted form, acetic acid is used as a weak acid for pH adjustment, preservation, and as a solvent in various laboratory processes.
Phosphoric acid (H3PO4): Phosphoric acid is used in laboratories for pH adjustment, buffer preparation, and as a reagent in biochemical and molecular biology experiments.
Citric acid (C6H8O7): Citric acid is a weak acid commonly used as a pH buffer, chelating agent, and in food and beverage industry applications.
Hydrofluoric acid (HF): Hydrofluoric acid is a highly corrosive acid used for glass etching, metal cleaning, and in certain specialized laboratory procedures.
These are just a few examples of the acids used in laboratory settings. It's important to note that working with acids requires proper safety precautions and appropriate training to handle them safely.
