ISO 9001, 14001, 18001, and 22001 are all international standards for quality management, environmental management, occupational health and safety management, and food safety management, respectively.

• ISO 9001 is focused on quality management systems and ensuring customer satisfaction.

• ISO 14001 is focused on environmental management systems and reducing environmental impact.

• ISO 18001 is focused on occupational health and safety management systems and ensuring a safe workplace....read more

To make sulfuric acid 1 normal, dilute 1 mole of sulfuric acid to 1 liter of water. To make 1 molar solution, dissolve 1 mole of sulfuric acid in 1 liter of water.

• To make 1 normal solution, dilute 1 mole of sulfuric acid to 1 liter of water

• To make 1 molar solution, dissolve 1 mole of sulfuric acid in 1 liter of water

Molecular weight is the sum of the atomic weights of all atoms in a molecule, while equivalent weight is the weight of a substance that reacts with or replaces one mole of hydrogen ions.

• Molecular weight is expressed in atomic mass units (amu) or grams per mole (g/mol).

• Equivalent weight is expressed in grams per equivalent (g/eq) or milliequivalents per gram (meq/g).

• Molecular weight is used to calculate the amount of a substance in a given volume or mass.

• Equivalent weight is u...read more

Temperature increases more than 100 'c of boilers steam due to pressure buildup and superheating.

• Boilers are designed to produce steam at high pressure and temperature.

• The pressure buildup causes the boiling point of water to increase, resulting in superheated steam.

• Superheated steam is used in various industrial processes that require high temperatures.

• The temperature increase can also be due to the addition of heat from external sources.

• Proper maintenance and monitoring of ...read more

To make 0.1 normal solution, dissolve 1.6g of NaOH in 1L of distilled water.

• Calculate the molecular weight of the solute

• Determine the molarity of the solution

• Calculate the volume of solvent needed

• Weigh the solute and dissolve in the solvent

• Adjust the volume of the solution to the desired level

The ionic product of water is the product of the concentrations of hydrogen ions and hydroxide ions in water.

• The ionic product of water is also known as the dissociation constant of water.

• It is represented by the symbol Kw.

• At 25°C, the value of Kw is 1.0 x 10^-14 mol^2/L^2.

• Kw can be used to calculate the pH and pOH of a solution.

• The pH of pure water is 7, which means that the concentration of hydrogen ions and hydroxide ions is equal.

OHSAS stands for Occupational Health and Safety Assessment Series.

• It is a framework for managing and improving occupational health and safety.

• It provides guidelines for identifying and controlling workplace hazards.

• It helps organizations to comply with legal and regulatory requirements.

• It is often used in conjunction with ISO 9001 and ISO 14001 standards.

• Certification to OHSAS 18001 demonstrates an organization's commitment to health and safety.
