(a) The acidic behavior of an acid is due to the presence of hydrogen ions [H+ (aq) ions] which are produced only when acids are dissolved in water. In the absence of water,
acids do not produce hydrogen ions
and hence do not show acidic behavior. Due to the presence of these ions, rain water conducts electricity.
Why do acids not show acidic Behaviour in the absence of water Why does distilled water not conduct electricity where as rain water does?
Why do acids not show acidic behaviour in the absence of water? Answer: Acids do not show acidic behaviour in the absence of water
because the dissociation of hydrogen ions from an acid occurs in the presence of water only
. It is the hydrogen ions that are responsible for the acidic behaviour.
Why do acids not show acidic Behaviour in the absence of water Why does an aqueous solution of an acid?
The acidic behaviour of acid is due to the presence of hydrogen ions. The acids will not show its acidic behaviour in the absence of water, this is because
acids do not dissociate to produce H+ (aq) ions in the absence of water
.
Why do acids show acidic Behaviour only in the presence of water?
Acids have an acidic behaviour
due to the presence of hydrogen ions
. Since hydrogen ions can only be formed in the presence of water, water is required for acids to exhibit acidic behaviour.
Why does distilled water not conduct electricity but rainwater does?
Complete answer:
Distilled water is a pure form of water which does not contain any solute in it therefore it cannot conduct electricity
because it does not contain ions
while rain water contains dissolved salts and acids which dissociates in ions and conducts electricity.
Why acid and bases show acidic Behaviour only in aqua state not in solid state?
Acids cannot release H
+
ions in absence of water, only on dissolving in water acids release H
+
ions. Acids show acidic behaviour only
due to H
+
ions released in presence of water
.
Why does pure acetic acid does not conduct electricity?
Answer : Pure acetic acid does not conduct electricity because
pure acetic acid cannot dissociate into hydronium ion and acetate ions which are required for the conduction of electricity
. Note: On the other hand, acetic acid in water dissociates into hydronium ion and acetate ions for the conduction of electricity.
Do bases show basic Behaviour in absence of water?
Bases do not show basic behaviour
in the absence of water.
Why alcohol and glucose are not Categorised as acid?
In order to glow the bulb after the, the electrons should move from the solution in the opposite direction to the movement of positive charge. Result: The solution
of glucose and alcohol do not give up ${H^ + }$ions in their solution forms
, hence they are not classified as acids.
Which element is common to all acids?
(a)
Hydrogen
is the element which is common to all acids.
What happens when an acid or base is mixed with water?
Adding water to an acid or base
will change its pH
. Water is mostly water molecules so adding water to an acid or base reduces the concentration of ions in the solution. … This causes the pH of the alkali to fall towards 7, making the solution less alkaline as more water is added.
Why does HCl gas not show acidic Behaviour?
Answer : (i) Dry
HCl gas does not contain any hydrogen ions in it
, so it does not show acidic behaviour. … Hydrogen ions do not exist as H
+
ions in a solution, they attach themselves to the polar water molecules to form hydronium ions, H

What is meant by acid rain How is it harmful to aquatic organisms?
The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water
can leach aluminum from soil clay particles and then flow into streams and lakes
.
What’s the meaning of distilled water?
:
water that has been freed of dissolved or suspended solids and from organisms by distillation
(as for medical or chemical purposes)
What is class 10 distilled?
Distilled water: Distilled water is
water that has been boiled into vapour and condensed back into liquid in a separate container
. Impurities in the original water that do not boil below or near the boiling point of water remain in the original container.
Is sugar water a good conductor?
Because pure water has few ions, it
is a poor conductor
. Uncharged molecules that dissolve in water, like sugar, do not conduct electricity.
