Question

Acids dissolved in water produce _______.

Answer 1

Hint: In the given question, we have to find out what result is produced when an acid is dissolved or mixed with water. Acids are basically chemical substances that have a pH value less than $ 7 $ . They usually have a sour taste. We must take the required precautions when diluting the acid by adding it in water.

Complete answer:
So, Acidic substances when dissolved in water produce hydrogen ions, also called $ {H_3}O + $ particles.
An ion is either a particle, an atom, a molecule or a group of one of these with a frequent net electrical charge.
What exactly happens is that when acids are dissolved or mixed in water, the concentration of the ions of the acid or the acidic solution is decreased and it becomes dilute in nature. So, when the ions of an acidic solution are diluted with water, hydrogen ions are formed. Thus the pH level of the acidic solution also increases towards seven but the acidic nature decreases.
This reaction of acids with water is an exothermic reaction, which evolves heat in the process. This is the reason why we are advised to take precautions while diluting an acid. The acid should always be added dropwise to water as the reaction produces a lot of heat. Water should not be added to acid as the reaction will be highly exothermic and the beaker might break.
So, the answer we get for the blank is: Acids dissolved in water produce hydrogen ions.

Note:
We must have a clear understanding on the topic of acids and bases to solve such theoretical questions. The predominant concepts of the pH scale, diffusion, chemical equations and the results formed out of them should be at one’s fingertips.
