Meghmani Organics Production Chemist Interview Questions and Answers

Acidity is the measure of the concentration of hydrogen ions in a solution.

• Acidity is measured on the pH scale, which ranges from 0 to 14.

• A pH of 7 is neutral, while a pH below 7 is acidic and above 7 is basic.

• Acidity can affect the properties and behavior of substances, such as their solubility and reactivity.

• Examples of acidic substances include vinegar, lemon juice, and battery acid.

Indicators are used in quality control to determine the endpoint of a reaction or to indicate the presence of a specific substance.

• Indicators are used in titrations to determine the endpoint of a reaction.

• They can also be used to indicate the presence of a specific substance in a sample.

• Common indicators include litmus paper, phenolphthalein, and methyl orange.

• Indicators can be organic compounds or inorganic compounds.

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

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

• The point at which the reaction is complete is called the endpoint.

• The endpoint is usually detected using an indicator, which changes color when the re...read more

pH is a measure of acidity or basicity of a solution. It is the negative logarithm of hydrogen ion concentration.

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

• Acidic solutions have a pH less than 7, while basic solutions have a pH greater than 7

• pH can be measured using a pH meter or pH paper

• pH can also be calculated using the formula pH = -log[H+], where [H+] is the hydrogen ion concentration
