Bulb glows when the solution of hydrochloric acid is used, because it dissociates into hydronium ion in aqueous solution. Answer: Hydronium ions are responsible for behavior as acid. Acids do not dissociate into hydronium ions in the absence of water, hence they do not show acidic behavior in absence of water.

A fuse is a safety device made up of a conducting material having low melting point. It works on the principle of heating effect of current.

When the terminals of the bulb are connected with that of the electric cell by wires, the current passes through the filament of the bulb. This makes the bulb glow. Sometimes an electric bulb does not glow even if it is connected to the cell. This may happen if the bulb has fused.

the bulb does not glow in glucose solution and alcohol solution… they contain only covalent bonds which are formed by sharing of electrons…they don’t have any ions….that is why the bulb does not glow….

Answer: Bulb glows when the solution of hydrochloric acid is used, because it dissociates hydronium ion in aqueous solution. But glucose and alcohol do not dissociate hydronium ion in the water, which is responsible for the conduction of electricity. Hence solution of glucose and alcohol do not conduct electricity.

Ans. Alcohols and glucose though contain hydrogen but do not ionise in the solution to produce H+ ions. This is proved by the fact that there solutions do not conduct electricity.

No, for a solution to conduct electricity, presence of free ions is necessary, hence alcohol, which doesn’t ionise is a bad conductor of electricity. No. Pure alcohol don’t have free moving ions to carry electrical charges.

Alcohol solution is slightly acidic. Glucose solution is neutral.

due to such non dissociative property of glucose and alcohol, they do not show acidic properties. because there ions are not free to move. Although aqueous solution of glucose and alcohol contain hydrogen, these cannot dissociate in water to form hydrogen ions. Hence, they do not show acidic character.

Both acids and bases are electrolytes which means that they’re good conductors of electricity. Acids and bases both produce ions in water solution. Acids release hydrogen ions (H+) whereas Bases release hydroxide ions (OH-). The process of mixing acid or a base in water is an exothermic one.
