Hitachi Cash Management Services Cashier Interview Questions and Answers

Titration is a laboratory technique used to determine the concentration of a substance in a solution.

• Titration involves adding a solution of known concentration to a solution of unknown concentration until a reaction is complete.

• Types of titration include acid-base titration, redox titration, and complexometric titration.

• In acid-base titration, an acid or base is titrated with a solution of the opposite type to determi...read more

A pH meter is a scientific instrument used to measure the acidity or alkalinity of a solution.

• It measures the concentration of hydrogen ions in a solution.

• The pH meter consists of a pH probe and a meter that displays the pH value.

• The probe is inserted into the solution and measures the voltage difference between the solution and a reference electrode.

• The pH value is calculated based on the voltage difference.

• Examples o...read more

Concentration conversions refer to the process of converting between different units of concentration, such as molarity, molality, and percent composition.

• Converting between molarity and molality involves taking into account the density of the solution.

• To convert from molarity to percent composition, you need to consider the molar mass of the solute.

• Concentration conversions are important in chemistry for accurately me
