1) Give reasons for the following (a) HCl and HNO3 show acidic characters in aqueous solution while glucose and alcohol solution do not show acidic character even though they contain hydrogen. (b) Dry HCl does not change the color of dry litmus paper.
Answers
Bhai, ye chemistry hai, physics nahi
but, ye lo apka answer
a) Glucose and alcohols have +I group which reduces the polarity of the -OH bond present, hence reducing the acidity
b) This is because dry HCl gas does not contain H+ ions. It is only in the aqueous solution that an acid dissociates to give ions. Since in this case, neither HCl is in the aqueous form nor the litmus paper is wet.
please mark me brainliest
Answer:
It all happens because of H+ ion
Explanation:
HCl and HNO3 lefts some H+ ion in the aqueous solution which turns into H3O+ ion which actually shows acidity .alcohol also show this character but in very less number. But when they are dry they do not left protons.And glucose is a very much stable potion.That's why it does not show the acidic character.
Sorry if my answer is incorrect or is not understood by you.I am little weak in english
