Ionic Equilibrium 1

Question 1

Types of electrolyte

Answer 1

Strong electrolyte = degree of dissociation is 1,
Strong acids = H2SO4, HCI, HNO3,HCIO4
Strong base = KPH,NaOH
Salt = NaCL, KCI,CuSO4
Weak electrolyte
Weak acid = HCN, CH3COOH,HCOOH
Weak base = NH4OH, Cu( OH)2,Zn( OH) 2
Degree of dissociation is less than

Question 2

Formula of degree of dissociation

Answer 2

No.of moles dissociated /no. Of moles taken initially

Question 3

On dilution

Answer 3

Degree of dissociation increases

DOD = root volume

Question 4

On increasing temperature

Answer 4

The degree of dissociation increases

Question 5

DOD , DI ELECTRIC CONSTANT of solvent

Answer 5

Directly proportional

Question 6

H2o or d2o me kiska dielectric constant constant hoga

Answer 6

H2o ka zada hoga

Question 7

Difference between common ion effect or odd ion effect

Answer 7

Common ion effect hamara DOD decrease karta hai equilibrium ko reverse direction me Daal kar
Common ion effect DOD ko increase karta hai by shifting the equilibrium in forward directions

Question 8

Formula of dissociation constant of weak electrolyte

Answer 8

= c r²/1-r
r = alpha
C = moles / volume
And for 1 moles
r² / ( 1-r) v

Question 9

r = root volume when

Answer 9

When for weak electrolyte 1– alpha ≈ 1

Question 10

At infinite dilution the DOD FOR WEAK ELECTROLYTE

Answer 10

Is max = 1

Question 11

Arrhenius theory says
Ionic compound can divide in to opposite charged particle
Acid give h+
Strong acid give maximum no of h+, ka value is high
