Question

the pH of salt used to make tasty and crispy pakoras is 14. identify the salt and write a chemical equation for its formation. list its two uses

Answer 1

The salt is Sodium Bicarbonate.

It is formed in the Solvay process by reaction of Ammonia, sodium Chloride and Carbon iv oxide.

It can also be formed by dissolving CO₂ in Sodium hydroxide to form Sodium carbonate then reacting it with excess CO₂ and water to form Sodium hydrogen carbonate.

THE EQUATIONS

CO₂(g) + 2NaOH(aq) ------------> Na₂CO₃(aq) + H₂O (l)

Na₂CO₃(aq) + H₂O(l) + CO₂(g) -----------> 2NaHCO₃(aq)

USES

1.) It is used in baking.

2.) It is used to control pests.

Answer 2

Hey there! ☺☻☺

The pH of salt used to make tasty and crispy pakoras  is 9. 

The baking soda is most commonly used in making tasty pakoras because it's basic in nature. It's chemically known by the name sodium bicarbonate.

The reaction that take place during cooking of food and adding baking soda in it is as follows:

$2NaHCO_3 \xrightarrow[\text{}]{\text{heat}} Na_2CO_3 + H_2O + CO_2\\~~~~sodium~~~~~~~~~~sodium~~~(water)~~~\\~~~~bicarbonate~~~~carbonate$

Uses of Baking Soda are:

1. Sodium bicarbonate is a very effective product to eliminate the annoying black spots that often appear in the T area of the face, since its rough texture helps to deeply clean clogged pores. For this you should simply mix a spoonful of baking soda with a little milk and apply it directly to the affected area. Leave on for 15 minutes and rinse with warm water.

2.A tub bath with bicarbonate eliminates vaginal infections caused by yeast. Gargling baking soda prevents flu and throat infections. Take with water as antacid to avoid heartburn and heartburn. Mix with vinegar and put in the bites of bees or other insects. Make a paste with water for stings of ants, stingrays or spiders. Put on the skin exposed to poisonous wound to extract the poison and dry the wound.
