Question

For this assignment, write a paper about a baking soda of interest that is either manufactured or purified from natural sources. In the body of the paper, address the following questions:

• Who discovered the baking soda and when?
• If naturally occurring, where is it found?
• Who manufactures or purifies it?
• What are the common physical and chemical properties?
• What are the common uses?
• Is it harmful? Describe and explain its effects.

Answer 1

1. In 1791, French chemist Nicolas Leblanc produced sodium carbonate, also known as soda ash.

2. It is found in natural occuring mineral called nahcolite.

3. We can manufacture by solvay process .

4.physical properties:

Sodium bicarbonate is a white, crystalline powder that sometimes forms lumps. It is odorless and has a bitter, salty taste. At room temperature, it is a solid.

Chemical properties:

When heated to a temperature greater than 50 degrees C (122 degrees F), sodium bicarbonate decomposes, or splits apart to form mostly carbon dioxide (CO2) and water (H2O) with trace amounts of sodium carbonate (NaCO3).

Sodium bicarbonate is an amphoteric compound. Aqueous solutions are very mildly alkaline due to the formation of carbonic acidand hydroxide ion:

HCO​​​-3​ + H2O -------> H2CO3 + OH​​​​​-

5. USES:

1.In cooking, baking soda is primarily used in baking as a leavening agent. When it reacts with acid, carbon dioxide is released, which causes expansion of the batter and forms the characteristic texture and grain in pancakes, cakes, quick breads, soda bread, and other baked and fried foods.

2.Sodium bicarbonate can be an effective way of controlling fungal growth.

3.Sodium bicarbonate can be administered to pools, spas, and garden ponds to raise the total alkalinity.

4. In producing baking soda .

5.Sodium bicarbonate can be used to extinguish small grease or electrical fires by being thrown over the fire, as heating of sodium bicarbonate releases carbon dioxide.

* It is harmful in following ways:

1.Inhalation

Breathing in sodium carbonate could irritate your lungs or worsen conditions such as acute or chronic asthma or another chronic pulmonary disease. Inhalation could irritate your nose, throat or respiratory tract.

2.Swallowing

If sodium carbonate is swallowed, especially in a large amount, call for medical help immediately. Sodium carbonate can burn your mouth, throat, stomach or esophagus, and vomiting, nausea or diarrhea could result.

3.Skin and Eye Irritation

Your skin could become irritated after prolonged or repeated contact with sodium carbonate, causing redness or swelling. If you already have a skin condition, such as skin lesions, sodium carbonate could further irritate this. If your skin is already moist, sodium carbonate could cause chemical burns.
