0.002M HCl means 0.002 moles HCl in 1L solution.
Therefore 0.02 moles HCl in 10L solution.
pH = 2-log2
= 2-0.3010
= 1.6990
- log(0.00450 M HCl)= 2.3 pH=======
Since HCl is a strong acid it completely dissociates. Therefore [H+] = [HCl] and this case = 0.25 M. pH = -log [H+] = 0.602
.260 M of HCL, not 260 More than likely correct, but, - log(0.260 M HCl) = 0.6 pH ----------- ( pH can be below 1 )
A 0.1 M concentration of HCl corresponds to a pH of 1.0.
The pH of a 0.140 M HCl solution is approximately 0.85. This is because HCl is a strong acid that completely dissociates in water to give H+ ions, resulting in a low pH.

its PH is 3
A 0.1 M concentration of HCl corresponds to a pH of 1.0.
The pH of a 0.140 M HCl solution is approximately 0.85. This is because HCl is a strong acid that completely dissociates in water to give H+ ions, resulting in a low pH.
The pH of a 0.25 M HCl solution is approximately 0.60. This is because HCl is a strong acid that dissociates completely in water to form H+ ions, resulting in a high concentration of H+ ions and a low pH.
No, pH 2.0 HCl refers to the acidity level of the solution, while 0.1 M HCl refers to the molarity or concentration of the hydrochloric acid. The two terms describe different properties of the solution.
HCl liberates 1M of H+ Ions per mole of HCl so 0.034M HCl = 0.034 M H+ Ions as pH = -log10 [H+] where [] means the conc. pH= -log10 [0.034]
25g HCl 1 mol 36.46g HCl =.686 mol M=.686 mol/1.5 L=.457M pH= -log(.457) pH= .34
The pH of a 0.0020 M HCl solution is approximately 2.7. This is because HCl is a strong acid that completely dissociates in water to form H^+ ions, decreasing the pH of the solution.
The pH of a 0.01 M solution of HCl in water would be approximately 2, since HCl is a strong acid that completely dissociates in water to form H+ ions. This high concentration of H+ ions results in a low pH value.
