Chemical name and formula are identifiers for specific chemical compounds.

• Chemical name is the common name given to a chemical compound.

• Chemical formula represents the elements and their ratios in a compound.

• Example: Water - Chemical name, H2O - Chemical formula.

To make 0.1M HCL, dilute concentrated hydrochloric acid with water.

• Dilute 1 part of concentrated HCL with 9 parts of water to make 0.1M HCL solution.

• Always add acid to water slowly to prevent splashing and heat generation.

• Use proper protective equipment such as gloves and goggles when handling acids.

Operation and calibration of instrumentation involves understanding how to use and adjust various tools and equipment for accurate measurements.

• Understand the purpose and function of each instrument

• Follow manufacturer's instructions for operation and calibration

• Regularly calibrate instruments to ensure accuracy

• Keep detailed records of calibration and maintenance

• Train staff on proper use and calibration procedures

Normality is a measure of concentration in chemistry, expressed as the number of equivalents of a solute per liter of solution.

• Normality is similar to molarity, but takes into account the number of equivalents of a solute rather than just the number of moles.

• It is calculated by dividing the number of equivalents of solute by the volume of solution in liters.

• For example, a 1M solution of HCl is also 1N, since HCl is a m
