Explain why pure hydrogen cyanide does not conduct electricity, but become a conductor when it is dissolved in water?

Chemistry

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

HCN--->H^{+}(aq)+CN^{-}(aq)

These ions obtained due to dissociation of HCN makes it conducting in nature.

KonstantinChe [14]

Explanation:

Carbon-12 atoms have stable nuclei because of the 1:1 ratio of protons and neutrons.

Carbon-14 atoms have nuclei which are unstable. C-14 atoms will undergo alpha decay and produce atoms of N-14. Carbon-14 dating can be used to determine the age of artifacts which are not more than 50,000 years old.

Which member of each pair is more soluble in diethyl ether? Why?<br> (c) MgBr₂(s) or CH₃CH₂MgBr(s)
White raven [17]

CH3CH2MgBr is more soluble in diethyl ether .

We know that polar solvent dissolve in polar solvent very perfectly . as diethyl ether is a polar solvent so it have dipole -dipole interaction .

Hence the compound with similar interaction can dissolve in diethyl  ether .

Here , MgBr2  is an ionic compound . there is ion-ion interactions occurs which is not similar to dipole -dipole interaction in diethyl ether .hence the solubility of MgBr2 in diethyl ether is less .

but in case of CH3CH2MgBr there are both polar and nonpolar end .CH3CH2 is the nonpolar end and MgBr is the polar end .

thus with the nonpolar end solute interact using depression forces and with polar end solute interact using dipole-dipole interaction . so CH3CH2MgBr is more soluble .

You are comparing a reaction that produces a chemical
MaRussiya [10]

If the reaction is a chemical change, new substances with different properties and identities are formed. This may be indicated by the production of an odor, a change in color or energy, or the formation of a solid.
