Hard water contains high levels of minerals like calcium and magnesium. DM water is demineralized water with all impurities removed.

• Hard water has high levels of minerals like calcium and magnesium

• DM water is demineralized water with all impurities removed

• Hard water can cause limescale buildup in pipes and appliances

• DM water is used in industries like pharmaceuticals and electronics for its purity

pH is a measure of acidity or alkalinity on a scale of 0-14. The pH of our skin is typically around 4.7-5.75.

• pH stands for 'potential of Hydrogen' and measures the acidity or alkalinity of a substance on a scale of 0-14.

• A pH of 7 is considered neutral, below 7 is acidic, and above 7 is alkaline.

• The pH of our skin is typically around 4.7-5.75, making it slightly acidic to help protect against harmful bacteria and fungi.

A centrifuge is a machine that spins samples at high speeds to separate components based on their density.

• Load samples into centrifuge tubes and balance the tubes in the rotor

• Select appropriate speed and time settings based on the sample type and desired separation

• Start the centrifuge and wait for it to reach full speed before stopping it and removing the separated components

• Clean the centrifuge and rotor after use to prevent contamination

Hard water contains high mineral content, while soft water has low mineral levels, affecting usage and health.

• Hard water is rich in calcium and magnesium ions, while soft water has fewer of these minerals.

• Hard water can cause scale buildup in pipes and appliances, reducing efficiency.

• Soft water is often treated with sodium ions, making it less likely to form scale.

• Examples of hard water sources include well water and certain municipal supplies.

• Soft water is commonly produced ...read more

Normality measures reactive capacity, while molarity measures concentration of solute in a solution.

• Normality (N) is the number of equivalents of solute per liter of solution.

• Molarity (M) is the number of moles of solute per liter of solution.

• Example: 1N HCl has 1 equivalent of H+ per liter; 1M HCl has 1 mole of HCl per liter.

• Normality is used in acid-base reactions, while molarity is commonly used in general chemistry.

• For diprotic acids like H2SO4, 1M is 2N because it can do...read more

Maintain stock by creating a week-wise plan based on sales data and inventory levels.

• Analyze sales data to determine demand for each product

• Review inventory levels to ensure sufficient stock for upcoming weeks

• Create a week-wise plan for ordering and receiving new stock

• Adjust plan as needed based on changes in demand or inventory levels

• Use inventory management software to track stock levels and monitor sales trends

pH is a measure of the acidity or alkalinity of a solution, indicating its hydrogen ion concentration.

• pH scale ranges from 0 to 14, with 7 being neutral.

• A pH less than 7 indicates acidity (e.g., lemon juice, pH 2).

• A pH greater than 7 indicates alkalinity (e.g., baking soda, pH 9).

• pH is crucial in various fields, including chemistry, biology, and environmental science.

I can resolve my pain areas by identifying the root cause and implementing effective solutions.

• Conduct a thorough analysis of the production process to identify pain points

• Collaborate with team members to brainstorm and implement solutions

• Regularly review and evaluate the effectiveness of implemented solutions

• Stay up-to-date with industry trends and best practices to continuously improve processes

My strength is attention to detail and my weakness is sometimes being too critical of myself.

• Strength: Attention to detail - I am meticulous in my work and always strive for perfection.

• Weakness: Being too critical of myself - I tend to be hard on myself when things don't go as planned.

• Example: In my previous role, my attention to detail helped me identify and rectify errors in the quality control process.

• Example: However, I have learned to balance this by focusing on the posi...read more

Viscosity is the measure of a fluid's resistance to flow.

• Viscosity is affected by temperature and pressure.

• It is measured in units of poise or centipoise.

• High viscosity fluids are thick and flow slowly, while low viscosity fluids are thin and flow quickly.

• Examples of high viscosity fluids include honey and molasses, while water and alcohol are low viscosity fluids.
