Question

(1) What is the relationship, if any, between the following pairs of substances :
a) Strong electrolyte and strong acid or base.
b). Weak electrolyte and weak acid or base.
c). The cause of the differences in the conductances (currents) of isomolar solutions of KNO3 and Ca(NO3)2 (1) What is the relationship, if any, between the following pairs of substances :

b). Weak electrolyte and weak acid or base.
c). The cause of the differences in the conductances (currents) of isomolar solutions of KNO3 and Ca(NO3)2
a) Strong electrolyte and strong acid or base.
b). Weak electrolyte and weak acid or base.
c). The cause of the differences in the conductances (currents) of isomolar solutions of KNO3 and Ca(NO3)2

Explanation / Answer

a) Strong acids or strong bases are the best examples for strong electrolytes.

b) Weakacids or weakbases are the best examples for weakelectrolytes.

c) differences in the conductances (currents) of isomolar solutions of KNO3 and Ca(NO3)2 is due to the difference in the number of ions produced by the solutions. Since KNO3 produces 2 moles of ions and  Ca(NO3)2 produces 3 moles of ions,  Ca(NO3)2 exhibit the higher conductance.
