  • Acid + Alcohol = Ester
  • It is a chemical reaction that forms at least one ester.
  • Esters are produced when acids are heated with alcohol.

Additional Information

• Crystallization -
  • The process of obtaining a pure solid in the form of crystals from a saturated solution is called crystallization.
  • In crystallization, the solution is first evaporated to separate a solid from the solution.
  • When the solution becomes very concentrated, the solution is cooled slowly by stopping evaporation, causing crystals to form.
• Saponification -
  • The saponification of a fat or oil is done by using NaOH solution for the hot process.
  • Saponification to the sodium salt of myristic acid takes place with NaOH in water.
  • Soap is formed by a chemical reaction by heating an aqueous solution of vegetable oil or fat and caustic soda or caustic potash, and glycerol is liberated.

• On 2nd February 2021, India’s first Centre for Wetland Conservation and Management has been set up in Chennai.
• There are 42 wetlands in India that have international importance and hence recognized as the Ramsar Sites in India. Ramsar Sites are wetlands that have international importance.

Three Pillars:

• ​Under the “three pillars” of the Convention, the Contracting Parties commit to:
  • work towards the wise use of all their wetlands;
  • designate suitable wetlands for the list of Wetlands of International Importance (the “Ramsar List”) and ensure their effective management;
  • cooperate internationally on transboundary wetlands, shared wetland systems, and shared species.

The Montreux record:

• The Montreux Record is a register of wetland sites on the List of Wetlands of International Importance where changes in ecological character have occurred, are occurring, or are likely to occur as a result of technological developments, pollution, or other human interference.
• It is maintained as part of the Ramsar List.
