Since the beaker was heated we can asume that only magnesium cloride is left in the beaker, therfore the difference between the beaker with magnesium chloride and the empty beaker give the mass of magnisium chloride:
Explain why pure hydrogen cyanide does not conduct electricity, but become a conductor when it is dissolved in water?
1 answer:
Generally we have to kinds of conductors
a) metallic conductors: which conduct electricity due to free movement of electrons
b) electrolytic conductors: which conduct electricity due to movement of ions.
HCN is an electrolyte and is non conducting in pure state as it has no free ions or electrons
When HCN is dissolved in water it dissociates as
These ions obtained due to dissociation of HCN makes it conducting in nature.
