Question

What is hydrochloric acid on the pH scale?

Answer 1

pH scale

1. The pH scale is the scale that defines the acidic or basic strength of the solution. pH ranges from 1-to 14.
2. The pH is the negative log of hydrogen ions concentration.

Types of solution on basis of pH value

1. The pH ranges from 0 to 14 where 7 is neutral and below 7 it is acidic and above which it is basic.
2. So, pH defines the strength of the solution whether it is acidic, basic, or neutral.

pH value of Hydrochloric acid $\left(\mathrm{HCl}\right)$-

1. Hydrochloric acid ($\mathrm{HCl}$) is a strong acid and is a major component of gastric acid for the digestion of humans and most animals.
2. Hydrochloric acid is also known as muriatic acid.
3. It is a colorless solution with a pungent smell.
4. It is used as an acidifying agent.
5. It is a strong acid so its pH will be less than 7.
6. Its pH ranges from 1.5 to 3.5.

Temperature effect on pH-

1. An increase in temperature also increases the molecular vibration of concentration of $\left[{\mathrm{H}}^{+}\right]$ ion for this decreases the tendency to forming hydrogen bonds, thus leading to a reduction in pH.
