Chemistry Demystified Udayalakshmi Bhamidipalli

This is the third episode of the series on Acids, Bases and Salts. In this episode, we discuss the properties of acids and bases.
Properties of Acids
Physical Properties: 
Sour in taste.
Highly corrosive.
 Chemical Properties:Acid (Dil.) + Active Metals*
2HCl (Dil.) + Mg = MgCl2 + H2
2Al + 6HCl = 2AlCl3 + 3H2
Salt + H2 (*Active Metals – MAZFE – Magnesium, Aluminium, Zinc, Iron) 
o Metallic (Bi)Carbonates + Acid (Dil.) Metallic Salt + CO2 + H2O
*  Na2CO3 + HCl (Dil.) NaCl + H2O + CO2
*  NaHCO3 + HCl (Dil.) NaCl + H2O + CO2
o Metallic (Bi)Sulphites + Acid (Dil.) Metallic Salt + SO2 + H2O
* Na2SO3 + HCl (Dil.) NaCl + H2O + SO2
* NaHSO3 + HCl (Dil.) NaCl + H2O + SO2
o Metallic Sulphides + Acid (Dil.) Metallic Salt + H2S (Rotten Egg Smell) o FeS + HCl FeCl2 + H2S (Rotten Egg Smell)
Properties of Bases
Neutralization: Acid + Base = Salt + Water
 HCl+NaOH = NaCl+H2Oo Ammonium Salts + Alkali = Salt + Ammonia + Water
 NH4Cl + NaOH = NaCl + NH3 + H2O
Reaction of alkalis with metal salt solutions:
* CuSO4 + 2NaOH = Cu(OH)2 + Na2SO4
Pale blue ppt
* ZnSO4 +2NaOH = Zn(OH)2 + Na2SO4
Gelatinous white ppt
* Zn(OH)2 + 2NaOH = Na2ZnO2 + 2H2O
* Pb(NO3)2 + 2NaOH = Pb(OH)2 + 2NaNO3
Chalky white ppt
* Pb(OH)2 + 2NaOH = Na2PbO2 + 2H2O
* FeSO4 + 2NaOH = Fe(OH)2 + Na2SO4
Dirty green ppt
* FeCl3 + 3NaOH = Fe(OH)3 + 3NaCl
Reddish brown ppt
