The document outlines the physical and chemical properties of acids, bases, and salts, including examples of each. It explains how acids taste sour, turn blue litmus red, and react with bases and carbonates to form salts. Bases are described as bitter, turning red litmus blue, and also reacting with acids to create salts, alongside the classification of strong and weak bases.

2. ACIDS
Physical Properties:-
 Sour in taste
For eg:-Orange,Lemon
Que: Give any other example.
 Turns blue litmus to red
+Acids =

3. Chemical Properties Of Acics
Acids reacts with Base to form salts
For Eg.:-
H2SO4 +NaOH = Na2SO4 +H2O
Que : Give any other reaction.
Acids reacts with carbonates to form
salts,water,CO2
For Eg.:-
HCL+Na2CO3 =NaCL+H2O+CO2

4. EXAMPLES OF ACIDS
Organic Acids:-
Vitamin C
(Citrus Fruits)
Minerals Acids:-
. HCL
. H2SO4
. HNO3

5. Bases
 Physical Properties:-
Turns Bitter in taste
Red litmus to blue
 Chemical Properties:-
Acid +Base =Salts
For Eg:-.
NaoH+HNO3 =NaNO3+ H2O

6. TYPES OF BASES
 Strong Bases:-
For Eg.:- NaOH
KOH
 Weak Bases:-
NH4OH
Que. Is Mg(OH)2 is strong base?
Que. CaSO4 is a strong base or weak?

7. SALTS
Physical Properties:-
/ Salty in taste
/ Put no effect on
the litmus paper
/ Neutral in nature
Que: How salt is neutral ?

8. TYPES OF SALTS
1. Acid Salts:-
For Eg.
Strong Acid + WeakBase =Acid
Salts
HCL + NH4OH = NH4CL+H2O
2. Basic Salts:-
NaOH + CH3COOH = CH3COONa +H2O
Que: Give any other example of basic salts.

9. NEUTRAL BASES
Strong Acid +Strong Base
For Eg:-
HCL + NaOH = NaCL +H2O
Weak Acid + Weak Base
For Eg:-
CH3COOH + NH4OH
=CH3COONH4+H2o
