Acid is stored in glass containers instead of iron containers to prevent chemical reactions that could contaminate the acid or cause dangerous reactions.

• Glass is non-reactive with most acids, preventing contamination of the acid.

• Iron containers can react with acids, leading to the formation of potentially dangerous byproducts.

• Glass containers are more chemically inert and do not corrode when in contact with acids.

• Using...read more

Cleaning involves removing dirt, contaminants, and impurities from surfaces or materials using various methods and agents.

• Identify the type of surface or material to be cleaned (e.g., glass, metal, fabric).

• Choose appropriate cleaning agents (e.g., detergents, solvents, disinfectants).

• Use mechanical action (e.g., scrubbing, wiping) to enhance cleaning effectiveness.

• Rinse thoroughly to remove any residues of cleaning age...read more

Chemistry is the study of matter, its properties, composition, and interactions.

• Chemistry involves understanding the structure and behavior of atoms and molecules

• It explores how substances react with each other to form new substances

• Chemistry is used in various industries such as pharmaceuticals, agriculture, and manufacturing

The number of batch changes in a reactor can vary depending on the production schedule and process requirements.

• The number of batch changes in a reactor is typically determined by the production plan and the capacity of the reactor.

• Factors such as reaction time, temperature, pressure, and product yield can also influence the frequency of batch changes.

• For example, a reactor used for continuous production may have fewer...read more

There are several classes in safety, including general safety, chemical safety, fire safety, electrical safety, and more.

• General safety covers basic safety practices and procedures for all employees.

• Chemical safety focuses on handling, storing, and disposing of hazardous chemicals.

• Fire safety includes fire prevention, evacuation procedures, and proper use of fire extinguishers.

• Electrical safety involves safe practices ...read more

ALCOA stands for Attributable, Legible, Contemporaneous, Original, and Accurate in the context of data integrity.

• Attributable - Data should be traceable to its source.

• Legible - Data should be clear and easy to read.

• Contemporaneous - Data should be recorded at the time of observation.

• Original - Data should be the first recording of the information.

• Accurate - Data should be error-free and true to the actual observation.

pH indicators, name reactions, and acid-base differentiation are important topics in chemistry.

• pH indicators are substances that change color depending on the pH of the solution they are in, such as litmus paper or phenolphthalein.

• Name reactions are specific chemical reactions that have been named after their discoverers or developers, such as the Grignard reaction or the Friedel-Crafts reaction.

• Acid-base differentiati...read more
