0.01 M HCI দ্রবণের pH কত?

The pH of a 0.01 M HCl solution is approximately 2.0.

Explanation:

Hydrochloric acid (HCl) is a strong acid, which means it completely dissociates in water to release hydrogen (H+) and chloride (Cl-) ions. The concentration of hydrogen ions in the solution is therefore equal to the initial concentration of the acid.

Steps to find pH:

Write the dissociation equation for HCl: HCl → H+ + Cl-

Identify the concentration of hydrogen ions: Since HCl is a strong acid, it completely dissociates, so the concentration of H+ ions is equal to the initial concentration of HCl: [H+] = 0.01 M

Use the pH formula: pH = -log10([H+])

Calculate the pH: pH = -log10(0.01) Using a calculator, you will find that pH is approximately 2.0.

Therefore, the pH of a 0.01 M HCl solution is approximately 2.0.
