Question

Sodium salts of some acids are very useful as food preservatives. If true enter 1 else 0.

Answer 1

Hint: Sodium salts are generally known as organic or inorganic salts. These salts are composed of sodium cation where we know cation is an ion positively charged ion and the conjugate base anion where anion is negatively charged ion.

Complete answer:
Sodium salts are generally formed by the neutralization of the acid with sodium hydroxide. Sodium salts are generally divided into two categories known as sodium salts of carboxylic acids like sodium formate or sodium salts of inorganic acids.
Food is the need of every human being, it is the necessity to survive. Nowadays life has become very busy that some people do not have much time to prepare their food so there is a very great option to preserve the food. Juices, jams, pickles etc are the things which can be preserved for a long time. Rather than this there are some frozen and readymade food items are also in the market so to preserve the food items we must needed some preservative agents.
Preservative agents should be off that type so that it will not react with our food or may not be of toxic nature which create any hazardous effects to our health.
Sodium benzoate which is sodium salt is one of the best preservatives.

So the correct option should be 1 i.e. true.

Note:
Sodium benzoate is a chemical substance represented by the chemical formula ${{C}_{6}}{{H}_{5}}COONa$ and here the presence of sodium ion indicates that it is of sodium salt and it is kept in the category of sodium carboxylic acids.
