7) Factors affecting the solubility in water:
Polarity, ionic and covalent nature, dissociation constant.
Water being polar compound more polar substances are more soluble
in water. Ionic compounds are more soluble in water. The compound
with higher dissociation constant will have higher solubility.
9) Conductance is mainly dependant on the dissociation of the
ionic compound.
Higher the dissociation constant, the higher the conductivity of
that aqueous solution.
1) AgCl: AgCl is spearingly soluble in water. Hence most of AgCl will be insoluble in water and very little amount will dissolve to give dissociated Ag+ and CI-ions. AgCl Electrolytic properties: As there are ions of Ag+ and Cl- present in the solution, the solution will show conductance. H2O 2) HNO3: is an ionic compound and strong acid hence it dissociates completly to give H+ and NO3- ions. HNO3 there wont be any HNO3 molecules • H+ Electrolytic properties: NO3- As there are high number of ions of H+ H20 and NO3- present in the solution, the solution will show high conductivity. 3) CaCl2: it is highly soluble in water and give Ca2+ and Cl-ions. CaCl2 Ca2+ Electrolytic properties: CI- As there are high number of ions of H+ and NO3- present in the solution, the solution will show high conductivity. H2O
4) CH3OH: This is a polar covalent compound. Practically, it does not dissociate as such in to the water. CH3OH Electrolytic properties: As there are no ions produced there 40 will not be any conductunce. Water and alcohol molecules from strong hydrogen bonding hence alcohol molecules are surrounded by water molecules. H2O 5) KOH: It is strong electrolyte and dissociates completely in the water. • KOH there wont be any KOH molecules • K+ Electrolytic properties: • OH- As there are high number of ions of K+ and OH- present in the solution, the solution will show high conductivity. H20 6) HF is a weak electrolyte and hence very small ammount of HF will be dissociated to give H+ and F. HF Electrolytic properties: • H+ As there are some ions of H+ and F- . F present in the solution, the solution will H2O show some conductivity.
