Density is the mass of a substance per unit volume, indicating how compact its particles are.

• Density is calculated using the formula: Density = Mass/Volume.

• Example: Water has a density of 1 g/cm³, meaning 1 cm³ of water weighs 1 gram.

• Materials with higher density, like lead, feel heavier than less dense materials like aluminum.

• Density can change with temperature; for instance, hot air is less dense than cold air.

Unit operations are fundamental processes in chemical engineering that involve physical changes in materials.

• Involves processes like filtration, distillation, and crystallization.

• Each unit operation can be analyzed independently.

• Examples include heat exchangers for heat transfer and reactors for chemical reactions.

• Unit operations are essential for designing and optimizing chemical processes.

A chemical reaction involves the transformation of substances through breaking and forming chemical bonds, resulting in new products.

• Chemical reactions can be classified into types: synthesis, decomposition, single replacement, and double replacement.

• Example of synthesis: 2H₂ + O₂ → 2H₂O (Hydrogen and oxygen combine to form water).

• Example of decomposition: 2H₂O → 2H₂ + O₂ (Water breaks down into hydrogen and oxygen).

KF reagent is a solution used in Karl Fischer titration to determine the water content in a sample.

• KF reagent is a specific solution used in Karl Fischer titration method

• It is used to accurately determine the water content in a sample

• The reagent reacts with water in the sample to produce a measurable result

• Commonly used in industries like pharmaceuticals, food, and chemical manufacturing

There are two types of analytical balance calibration: external calibration and internal calibration.

• External calibration involves using calibrated weights external to the balance.

• Internal calibration involves using built-in calibration weights within the balance.

• Both types of calibration are important to ensure accurate measurements.

• Regular calibration is necessary to maintain the accuracy of the analytical balance.
