What do u mean by saponification?

CBSE > Class 10 > Science

Yogita Ingle 5 years, 8 months ago

Saponification is the hydrolysis of an ester under acidic or basic conditions to form an alcohol and the salt of a carboxylic acid. Saponification is commonly used to refer to the reaction of a metallic alkali (base) with a fat or oil to form soap.

Example:

Ethanoic acid reacts with alcohols in the presence of a conc. sulphuric acid to form esters.

C₂H₅OH + CH₃COOH → CH₃COOC₂H₅ + H₂O

The ester, on treating with a base such as NaOH is converted back to alcohol and sodium salt of carboxylic acid. The reaction is known as saponification because it is used in the manufacture of soap.

CH₃COOC₂H₅ + NaOH → C₂H₅OH + CH₃COONa

Why do some states enjoy special powers in India. Which are they.

Yogita Ingle 5 years, 8 months ago

In a holding together federation (like India) , the country decides to divide its powers among a central authority as well as its constituent states. In a holding together federation the central government has more power than the state government and the states have unequal power. Some states have special powers. Jammu and Kashmir has a special constitution where a law passed by the central can only be passed if it is approved by the state assembly. The union territories have very little powers as they are too small to be considered as a seperate state and were not merged during state formation. The central government has special power in ruling these states.

Disadvantages of the napoleonic code are:-
. But this initial enthusiasm soon turned into hostility and opposition when it became visible that the new administrative arrangements do not go hand in hand with the political freedom. Censorship, taxation, forced conscription into the French armies required to conquer the rest of Europe, all seemed to outweigh the advantages of the administrative changes.
