SOLAR INDUSTRIES INDIA Quality Analyst Interview Questions, Process, and Tips

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 hydroxid

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

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

5S is a workplace organization method that aims to improve efficiency and productivity by eliminating waste and optimizing workflow.

• Sort - eliminate unnecessary items

• Set in order - organize remaining items

• Shine - clean and maintain workplace

• Standardize - establish procedures and guidelines

• Sustain - maintain and improve the system

• Example: organizing tools in a mechanic's garage

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 commi

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 ...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 f...read more
