Question

What is the characteristic property of acids?

Answer 1

Hint: As we know that acid – base chemistry is one of the most important chemistry that must be studied well and hence we must know the properties of each of them. Here we are asked about the common characteristic properties found in acids which are the hydrogen-containing substances that are capable of donating a proton (that is hydrogen ion) to another substance.

Complete answer:
The characteristic properties of acids are as follows:-
-Aqueous solutions of acids are electrolytes which mean that they can conduct an electrical current because of the dissociated ions.
-Acids have a sour taste which can also be tasted in citric fruits as they all contain acids as one of their components.
-Certain acid-base indicators change color in contact with acids. Two common examples of indicators are litmus paper and phenolphthalein where blue litmus turns red in the presence of an acid while phenolphthalein turns colorless.
-Acids react with metals to liberate hydrogen gas such as $Zn(s)+{{H}_{2}}S{{O}_{4}}(aq)\to ZnS{{O}_{4}}(aq)+{{H}_{2}}(g)$.
-When acids react with bases, they produce a salt compound and water which is known as neutralization reaction. When the same moles of an acid and a base react, the acid gets neutralized by the base.
-The pH of acids lies in between 0 to 6.9. Also strong acids are very corrosive in nature.

Note:
-Remember that some acids act as strong electrolytes because they ionize completely in water and yield a great number of ions whereas other acids act as weak electrolytes because they exist primarily in a non-ionized form when dissolved in water.
