Answer 1

Answer:

1) Acids and bases can be classified as organic or inorgani. Strong acids in solution produce a high concentration of hydrogen ions.

2) [a]Citric acid: As a preservative for food As a flavouring agent.

[b]Ascorbic acid : (also called vitamin c) In the treatment of bone marrow and scurvy diseases.

[c] Acetic acid: Added to pickles to make them sour.

3 Bases can be classified  as organic or inorganic. Strong bases in solution produce a high concentration of hydroxide ions and a correspondingly low concentration of hydrogen ions.

4)[a] Sodium hydroxide, NaOH (lye or caustic soda):Used in the manufacture of soaps and detergents and as the main ingredient in oven and drain cleaners.

[b] Potassium hydroxide, KOH (lye or caustic potash):Used in the production of liquid soaps and soft soaps. Used in alkaline batteries.

5] Some properties

. Bases change the colour of litmus from red to blue.

They are bitter in taste.

Bases lose their basicity when mixed with acids.

Answer 2

1.Acids are sour in taste and can change the blue litmus paper red and can react with metals to liberate hydrogen and can neutralise bases to form salts .So, acids can be defined as"An acid is a chemical compund which when dissolved in water,furnishes Hydrogen ions or more correctly Hydronium ions as the only postively charged ions .

$\ HCl+H_2O \rightleftharpoons \ H_3O^{+} +Cl^{-}$

Acids are classified on the basis of :-

1.Strength :- On the basis of strength acids are classified as;-

i)Strong acid:-The acid,which dissociates almost completely (i.e., undergoes almost complete ionisation ) in solution thereby producing a high concentration of hydronium ions ,is called a strong acid. For example:-

$\ HCl+ H_2O \rightleftharpoons \ H_3O^{+}+Cl^{-}$

ii)Weak acid:-The acids,which dissociate only partially in aqueous solution to produce a low concentration of hydronium Ions are called weak acids.for examples :-

$\ H_2CO_3+2H_2O \rightleftharpoons \ 2H_3O^{+}+CO_3^{2-}$

2.Some uses of acids are given below:-

i) Tartaric acid - In baking powder

ii) Carbonic acid- In cold drinks and soda water .

iii) Acetic acid - As vinegar .

3.A base is a chemical compund which reacts with hydronium ions furnished by an acid to form a salt and water only.

for example:-

$\ NaOH + HCl \rightarrow \ NaCl +H_2O$

Bases are classified on the basis of :-

1.Strength:- On the basis of strength Bases are also classified as ;-

i) Strong base:- The bases which dissociates almost completely that is undergo almost complete ionization in aqueous solution, thereby producing a higher concentration of hydroxyl ions are called strong bases . some examples of strong bases are KOH,NaOH etc..

ii)Weak base:- The bases which dissociate only partially in aqueous solution to produce low concentration of hydroxyl Ions are called weak bases .

4.Some use of bases are given below;-

i) Magnesium hydroxide - As an antacid

ii) Ammonium hydroxide-for removing grease stains from clothes.

iii)Aluminum hydroxide -As foaming agent in fire extinguishers.

5. General properties of bases are as follows:-

i) Bases are bitter in taste and are soapy to touch .

ii) Bases turn red litmus blue.

iii) Bases gives a pink color with phenolphthalein .

iv)It turn yellow from orange with methy orange.
