Answer 1

Answer:

i think ans is help you thanks

Answer 2

The source , strength and PKa of 4 different inorganic and organic acids are as follows:

[the details are provided in bulletin form and not tabular.]

Four inorganic acids:

1. Ammonia: NH3

• Source: It is monoprotic acid. The main use of ammonia is agricultural fertilizers especially in animal husbandry, where there is excess fertilization application based on NH3. It occurs and gets renewed naturally in the environment as a part of nitrogen cycle.
• Strength: It is weak base but also acts as weak acid under certain conditions.
• PKa: 9.24

2. Boric acid: H3BO3

• Source: It is a common boron compound and a chemical remedy for vaginal infections. It occurs in plants naturally including almost every fruit. It is also found naturally in sea water. Firstly, it was prepared from borax.
• Strength: It is a very weak acid.
• PKa: 9.24

3. Iodic acid: HIO3

• Source: It is formed by oxidation i.e when oxygen reacts with iodine. It is strongly oxidising in acidic solutions.
• Strength: It is very strong acid by nature.
• PKa: 0.75/0.78

4. Nitric acid: HNO3

• Source: Burning of some oraganic compounds containing nitrogen exhibits nitric acid. It is also produced by the source of amino acids-arginine present in some food items such as seeds and nuts.
• strength: It is one of the strongest acid and highly corrosive in nature.
• PKa: -1.37

Four organic acids:

1. Formic acid: HCOOH

• Source: It is commercially produced from sulphuric acid, & Carbon monoxide. It does naturally occur in ants, bee stings,etc. It is also found in fruits such as apples, strawberries,etc.
• strength: It is a stronger acid.
• PKa: 3.75

2. Citric acid: CH2COOH-C(OH)COOH-CH2COOH

• Source: It is naturally found in citric acid such as lemon, Orange,etc.
• strength: It is a weak acid.
• PKa: it has 3 different values 3.1, 4.7, and 6.4.

3. Oxalic acid: Presently, it occurs in dehydrated form C2H2O4·2H2O.

• Source:It is an oraganic compound that naturally occur in plants like tomato & spinach.
• strength: It is a strong acid as compared to acetic acid.
• PKa: 1.25 and 4.28(3) based on PKa1 & PKa2.

4. Tartaric acid: HO2CCH(OH)CH(OH)CO2H

• Source: Main natural sources of tartaric acid are plants such as tamarind, banana,apples, grapes, etc.
• strength: It is one among the strongest organic acids.
• PKa: 2.98 and 4.34 respectively for PKa1 & PKa2.

This is the details for the above question.
