An emergent property is a property which a collection or complex system has, but which the individual members do not.  
Water emergent properties: cohesion & adhesion, versatile solvent, temperature moderation, freezing.
The properties of a compound can be very different from the properties of the elements that make them, for example, Sodium is an explosive metal, and  Chlorine is a toxic gas, however, sodium chloride is a Delicious table salt!
 
        
             
        
        
        
All acids only conduct electric current when they are dissolved in water, because when they are in an aqueous medium, they undergo ionization, i.e. release <span>ions.</span><span>
HCl --> H</span>⁺ + Cl⁻
The bases also conduct electric current in solution, because the Ionic dissociation sufferers (release the existing ions in the formula) and molecular ionization, suffer the reacting with water and releasing ions.
NaOH ---> Na⁺  + OH⁻
hope this helps!
        
             
        
        
        
Answer:
