Question

Substance	Strong/Weak/Non	Molecular/Ionic	Ionize/Dissociate
Tap Water
Deionized Water
Table salt
Sucrose
Vinegar
Ethanol

Answer 1

The tap water contains dissolved solids like Ca and Mg ions of their salts and hence an electrolyte. Deionised water contains no dissolved solids and will not be an electrolyte. The ions of various salts, chemicals, minerals and and metals present in the tap water conduct electricity and whereas in pure water it contains very few of theses ions so it does not conduct electricity . Deionised water consists of hydrogen and oxygen molecules which are non-metals.

Table salt is NaCl which is a salt formed by neutralization reaction between strong acid HCl and strong base NaOH. Products of strong acid and strong base are strong electrolytes because they are fully dissociated in aqueous solutions. When table salt, sodium chloride, dissolves in water, it dissociates into its respective cations and anions, Na⁺ and Cl^-.  

Sucrose doesn't dissociate when dissolved in water, a property of non-electrolytes. The sugar water solution does not conduct electricity because it is a non-electrolyte. A sucrose solution exists as dissolved sugar molecules - not ions.

Vinegar  is an acid and aqueous. It is a weak electrolyte since it is a weak acid.

Ethanol is a non-electrolyte because it does not ionize when dissolved in water. It dissolves in water but does not dissociate into ions.

Substance	Strong/weak/Non	Molecular/Ionic	Ionize/Dissociate
Tap water	Weak electrolyte	Ionic	Ionize
Deionised water	Non-electrolyte	Molecular	Does not ionize or dissociate
Table salt	Strong electrolyte	Ionic	Dissociate
Sucrose	Non-electrolyte	Molecular	Does not ionize or dissociate
Vinegar	Weak electrolyte	Ionic	Ionize
Ethanol	Non-electrolyte	Molecular	Does not ionize or dissociate
