The pH of water decreases after adding HCl due to the increase in hydrogen ions. The resulting pH level depends on the amount of HCl added.
Adding hydrogen chloride to water the pH decrease.
The addition of HCl to a solution would decrease the pH, making it more acidic. This is because HCl is a strong acid that dissociates in water to release hydrogen ions, which increases the concentration of H+ ions in the solution and lowers the pH.
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.
- log(0.00450 M HCl)= 2.3 pH=======
The pH of 0.05 M HCl is 1.3. HCl is a strong acid that dissociates completely in water to release H+ ions, resulting in a low pH.
.260 M of HCL, not 260 More than likely correct, but, - log(0.260 M HCl) = 0.6 pH ----------- ( pH can be below 1 )
The pH of a 0.005N HCl solution is approximately 2.3. This is because HCl is a strong acid that dissociates completely in water to form H+ ions, leading to an acidic 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.
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 0.0020 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.
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
