Question

why does an aqueous solution of acid conduct electricity?​

Answer 1

Answer:

An aqueous solution of an acid conducts electricity because in water, an acid (HCl) dissociates to give ions. Since, the current is carried out by the movement of ions, an aqueous solution of acid conducts electricity. During dilution, more of acid dissociates into ions.Mar 29, 2019

Answer 2

Because most of the acids are composed of ions, the ions are electrically charged, so that the current can be conducted. Pure water does not conduct electricity because it does not carry ions.

Acid are ionized when they meet water to get ions, and the ions will get (provide) electrons after they are obtained (absorbed) by the power supply in the wire, so that the electrons in the circuit can continue to move directionally and get current. (follow the principle of electrolysis).

• Dilution involves more dissociation of acid into ions.

Classification

According to the number of hydrogen ions that can be generated by ionization of acid molecules, it can be divided into:

• Monobasic acid (HCl, HNO3 )
• Dibasic acid (H2SO4 , H2S, H2CO3 ) and
• Tribasic acid ( H3PO4 )

According to the presence or absence of oxygen atoms in the acid molecule:

• Oxygenated acid (H2SO4 , HNO3 , H3PO4 name: an acid)
• Oxygen-free acid (HCl, H2S name: hydrogen acid)

Nature

• It can react with alkali or alkaline oxide to form salt and water
• It can react with certain metals to form salts and hydrogen
• The aqueous solution has a sour taste and can make the indicator change color, such as purple litmus red.
