What is the purpose of sodium carbonate in part 1a

The diazotization of sulfanilic acid response is carried out in
water. Sulfanilic acid is insoluble in water usually, however when
sodium carbonate is added the SO3H group is deprotonated and also you
get the sodium salt which is soluble in water. Now that the
sulfanilic acid it might react with the nitroso anion to yield the
diazonium salt.
Sodium carbonate (also called washing soda or soda ash), Na2CO3
is a sodium salt of carbonic acid. It mostly happens as a
crystalline heptahydrate, which readily effloresces to kind a white
powder, the monohydrate. Sodium carbonate is domestically nicely
identified for its on a regular basis use as a water softener. It may be extracted
from the ashes of many vegetation. It’s synthetically produced in
giant portions from salt (sodium chloride) and limestone in a
course of generally known as the Solvay course of.The manufacture of glass is one
of a very powerful makes use of of sodium carbonate. When mixed with
silica and calcium carbonate and heated to excessive temperatures, then
cooled quickly, glass is produced. Any such glass is named
soda lime glass.
Sodium carbonate can be used as a comparatively robust base in
varied settings. For instance, sodium carbonate is used as a pH
regulator to keep up secure alkaline circumstances mandatory for the
motion of nearly all of photographic movie growing
Diazonium compounds or diazonium salts are a bunch of natural
compounds sharing a typical practical group R-N2+ X- the place R will be
any natural residue such alkyl or aryl and X is an inorganic or
natural anion akin to a halogen. Diazonium salts, particularly these
the place R is an aryl group, are necessary intermediates within the
natural synthesis of azo dyes..
Response of amine with the nitrosonium ion provides a diazonium salt.
The diazonium salt is often made in situ since it’s often
unstable. If the alkyl group is changed with an aryl group, the
salt is secure at 0 oC and reacts with varied nucleophiles.
