ICSE Class 10 Answered
It is an ionic compound which in the fused state or in aqueous solution allows the passage of an electric current and is decomposed by it.
Examples of electrolytes
Acids – H2SO4, HNO3, HCl, H3PO4
Bases – NaOH, KOH, NH4OH, Ca (OH) 2
Salts – NaCl, CuSO4 , PbBr2
Compounds which in their aqueous solution or in the fused state are almost completely ionised are called strong electrolytes.
Examples: Mineral acids, alkalis and salts
Compounds which in their fused state or aqueous solution are feebly ionised and are poor conductors of electricity are called weak electrolytes.
Examples: Acetic acid, oxalic acid
Compounds which neither in solution nor in the molten state allow an electric current to pass through them are called non-electrolytes.
Examples: Kerosene, carbon disulphide
