11 Copper is precipitated as sulphide in the II group while Zn is precipitated as sulphide in the IV group. Explain.
 
12 What is basic principle behind the systematic analysis of cations and group separation? Explain.
 
13 Differentiate between
a) hydrolysis and hydration
b) solubility and solubility product
 
14 Calculate the solubility of BaSO4 if its Ksp value is 1.1 x 10-10
 
15 10ml of 0.1M CaCl2 is mixed with 15ml of 0.11M NaF. Predict whether CaF2 will precipitate if the Ksp of CaF2 is 5.3 x 10-9.
 
16 Which of the following is more soluble?
a) AgCl or AgBr [ Ksp of AgCl = 1.8 x 10-10 ; AgBr = 5 x 10-13]
b) AgCN or Ni(OH)2 [ Ksp AgCN = 2 x 10-15; Ni(OH)2 = 6 x 10-17]
 
17 State (i) Henry’s law (ii) Law of mass action (iii) LeChatelier’s principle
 
18 Classify the following as Lewis acid or Lewis base
H+ , H2O , NH3 , BF3 , Al3+ , BeCl2 , Cl-
 
19 Write the formula for the conjugate acid of
(i) F- (ii) OH-
 
20 Write the formula for the conjugate base of HNO2 , HClO4 , OH-
 
21 A buffer solution contains 0.4mol of ammonium hydroxide and 0.5mol of ammonium chloride to make a buffer solution of 1L.Calculate the pH of the resulting buffer solution. Dissociation constant of ammonium hydroxide at 25oC is 1.81x 10-5
