Bliss Gvs Pharma Production Interview Questions and Answers

pH is a measure of acidity or alkalinity in a solution. It ranges from 0 to 14, with 7 being neutral.

• pH stands for 'potential of hydrogen'

• It is a logarithmic scale that measures the concentration of hydrogen ions in a solution

• A pH value below 7 indicates acidity, while a value above 7 indicates alkalinity

• Pure water has a pH of 7, which is considered neutral

• Examples of pH ranges: stomach acid (1.5-3.5), lemon juice (2-3

Molarity is a measure of the concentration of a solute in a solution.

• Molarity is defined as the number of moles of solute per liter of solution.

• It is denoted by the symbol 'M'.

• Molarity can be calculated using the formula: Molarity (M) = moles of solute / volume of solution (in liters).

• For example, if 0.5 moles of solute are dissolved in 1 liter of solution, the molarity would be 0.5 M.

A solution is a means of solving a problem or addressing a challenge.

• A solution is a specific action or set of actions that can be taken to resolve a problem.

• It involves identifying the problem, analyzing it, and implementing a plan to overcome it.

• Solutions can vary depending on the context and nature of the problem.

• For example, in production, a solution could be implementing a more efficient manufacturing process or i

Oxidation is a chemical process in which a substance loses electrons, resulting in an increase in its oxidation state.

• Oxidation involves the transfer of electrons from one substance to another.

• It often involves the addition of oxygen or the removal of hydrogen.

• Common examples of oxidation include rusting of iron and burning of fuel.

• Oxidation reactions are important in various industrial processes, such as the productio...read more

A strong acid is a chemical compound that completely dissociates into ions in an aqueous solution.

• Strong acids have a low pH value and are highly corrosive.

• They can react vigorously with other substances and can cause burns.

• Examples of strong acids include hydrochloric acid (HCl), sulfuric acid (H2SO4), and nitric acid (HNO3).

Boiling point is the temperature at which a substance changes from a liquid to a gas.

• Boiling point is a characteristic property of a substance.

• It is the temperature at which the vapor pressure of the liquid equals the atmospheric pressure.

• Different substances have different boiling points.

• Water boils at 100 degrees Celsius (212 degrees Fahrenheit) at sea level.

Reactors are vessels used in chemical processes to contain and control reactions.

• Batch reactor: used for small-scale production and testing

• Continuous stirred-tank reactor (CSTR): used for continuous production

• Packed bed reactor: used for catalytic reactions

• Fluidized bed reactor: used for gas-solid reactions

• Fixed bed reactor: used for heterogeneous reactions

Disintegration refers to breaking down into smaller pieces, while dissolution refers to a substance dissolving in a solvent.

• Disintegration is a physical process, while dissolution is a chemical process.

• Disintegration can occur due to physical forces like heat, pressure, or mechanical action.

• Dissolution occurs when a substance is mixed with a solvent and forms a solution.

• Examples of disintegration include breaking a roc...read more
