QUESTIONS
Why do HCI, HNO. ete.. show acidic characters in aqueous solutions
while solutions of compounds like alcohol and glucose do not show acidie
character?
Why does an aqueous solution of an acid conduct electricity?
PT why does dry HCl gas not change the colour of the dry litmus paper?
While diluting an acid. why is it recommended that the acid should be
added to water and not water to the acid?
How is the concentration of hydronium ions (H O') affected when a
solution of an acid is diluted?
How is the concentration of hydroxide ions (OH) affected when excess
base is dissolved in a solution of sodium hydroxide?

Answer:
Step-by-step explanation:
HCl and HNO3 dissociate in their ions or gives H+ ions in aqueous solution where alcohol and glucose does not gives H+ ions
Aqueous solution of an acid conduct electricity due to the presence of charged particles called ions in it.
Dry HCl gas does not change the colour of blue litmus paper to red because the separation of H+ ions from HCl molecule can occur only in the presence of water.
Because it is highly exothermic reaction
On diluting an acid, the concentration of hydronium ion (H3O+) in it decreases.
On dissolving more sodium hydroxide base in the same solution,the concentration of hydroxide ions (OH-) increases.
