A graph was plotted between molar conductivity of various electrolytes (NaCl, HCI and NH4OH) and C(in mol L-1). Correct setting :
I(NaCl), II(HCl), III(NH4OH)
I(HCI), II(NaCl), III(NH4OH)
I(NH4OH), II(NaCl),III(HCI)
I(NH4OH), II(HCI), II(NaCl)
A weak electrolyte gives a curved decreasing graph and strong electrolytes give straight-line decreasing graphs.
