MacDermid Enthone Industrial Solutions Trainee Quality Engineer Interview Questions, Process, and Tips

pH is a measure of acidity or alkalinity of a solution, ranging from 0 to 14.

• pH stands for 'potential of Hydrogen'

• It is a logarithmic scale, with 7 being neutral, below 7 acidic, and above 7 alkaline

• Examples: Lemon juice has a pH of around 2, pure water is around 7, and baking soda is around 9

Acids have a pH below 7 due to the presence of excess hydrogen ions.

• Acids release hydrogen ions (H+) in water, lowering the pH below 7.

• The pH scale ranges from 0 to 14, with 7 being neutral, below 7 acidic, and above 7 basic.

• Examples of acidic substances include lemon juice (pH 2), vinegar (pH 3), and battery acid (pH 1).

A buffer is a temporary storage area that holds data before it is processed or transferred.

• Types of buffers include input buffer, output buffer, circular buffer, and FIFO buffer.

• Buffers help in managing data flow between different components in a system.

• Examples of buffers include keyboard buffer, printer buffer, and network buffer.

Titration is a technique used to determine the concentration of a substance in a solution by reacting it with a known concentration of another substance.

• Titration involves slowly adding a solution of known concentration (titrant) to a solution of unknown concentration until the reaction reaches its endpoint.

• The endpoint is usually indicated by a color change or other observable change, such as a sudden pH shift.

• Common ...read more

Different types of titration include acid-base titration, redox titration, complexometric titration, and precipitation titration.

• Acid-base titration involves the neutralization of an acid with a base or vice versa.

• Redox titration involves a redox reaction between the analyte and titrant.

• Complexometric titration involves the formation of a complex between the analyte and titrant.

• Precipitation titration involves the form...read more
