Why do acids not show acidic behavior in the absence of water?
Rain water conducts electricity but distilled water does not. Why?
Why don’t we keep sour substances in brass and copper vessels?
Answers
Answer:
we don't keep sour substance in brass and copper substances because copper and brass are highly reactive with the acids and when they react with aids they spoil the substance that's kept in the vessel and it is also not good for health and can cause harm to health
Q- Why do acids not show acidic behavior in the absence of water?
Ans) Acids do not show acidic behavior in the absence of water because there is no production of H+ ions.
Acids are any inorganic or organic compounds with hydrogen atoms. Generally, most of the acids are considered to be weak. So, they dissociate into ions easily in the "polar solvents" such as water.The concept of acidic behavior rises due to the presence of H+ ions. The acids when dissolved in water only produce H+ ions. So, acid does not have any acidic behavior in the "absence of water".
Q- Rain water conducts electricity but distilled water does not. Why?
Ans) For conduction of electricity ions must be present. Distilled water is the most pure form of water so it does not have ions that help in the conduction of electricity . Since, there are no ions present in distilled water it does not conduct electricity. Whereas, in rainwater there are many ions present because it is an impure form of water . These ions dissociate hence help in conducting electricity in rainwater.
Q- Why don’t we keep sour substances in brass and copper vessels?
Ans) Sour substances like curd are acidic in nature. ,i.e, they have Acids present in them. So, when they are kept in brass or copper vessels, they react with them and form poisonous or toxic elements which may be harmful for the human body. Hence they are not kept in metal containers.
