Acids, Bases and Salts - Episode 3
Thursday, 4 June, 2020

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 AcidsPhysical Properties: Sour in taste.Highly corrosive. Chemical Properties:Acid (Dil.) + Active Metals*2HCl (Dil.) + Mg = MgCl2 + H22Al + 6HCl = 2AlCl3 + 3H2Salt + 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 + CO2o Metallic (Bi)Sulphites + Acid (Dil.) Metallic Salt + SO2 + H2O* Na2SO3 + HCl (Dil.) NaCl + H2O + SO2* NaHSO3 + HCl (Dil.) NaCl + H2O + SO2o Metallic Sulphides + Acid (Dil.) Metallic Salt + H2S (Rotten Egg Smell) o FeS + HCl FeCl2 + H2S (Rotten Egg Smell)Properties of BasesNeutralization: Acid + Base = Salt + Water HCl+NaOH = NaCl+H2Oo Ammonium Salts + Alkali = Salt + Ammonia + Water NH4Cl + NaOH = NaCl + NH3 + H2OReaction 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 This is a public episode.
