What is the pH of 0.0001M aqueous solution of hcl?
The pH of a 0.0001M aqueous solution of HCl is 4. The pH of a solution is calculated using the formula pH = -log[H+], where [H+] is the concentration of hydrogen ions in the solution. Since HCl is a strong acid that dissociates completely in water, the concentration of H+ ions in a 0.0001M solution of HCl is also 0.0001M.
Calculate the mole fraction of HCl in 20 percent aqueous solution?
The mole fraction of HCl in a 20% aqueous solution can be calculated by converting the percentage to a molarity concentration. Assuming the density of the solution is 1 g/mL, a 20% solution means 20g of HCl in 100g of solution. If the molar mass of HCl is 36.5 g/mol, we can calculate the molarity and then use it to find the mole fraction of HCl in the solution.
The pH of a 0.1 molar aqueous solution of HCl would equal -?
The pH of a 0.1 molar aqueous solution of HCl would be 1. This is because HCl is a strong acid that completely dissociates in water to produce H+ ions, resulting in a high concentration of H+ ions in solution, leading to a low pH value.
How do you standardise 0.1M HCl?
To standardize 0.1 M HCl, you would first need to titrate it against a solution of known concentration, usually sodium hydroxide (NaOH). By carefully adding the NaOH solution to the HCl solution until the reaction is complete, you can determine the exact concentration of the HCl solution. This process allows you to adjust the concentration of the HCl solution to the desired 0.1 M.
What is the molarity of H plus in an aqueous solution that is 0.17 M HCl?
The molarity of H+ ions in a 0.17 M HCl solution is also 0.17 M because HCl dissociates completely in water to yield H+ and Cl- ions. Therefore, the concentration of H+ ions is equal to the concentration of HCl in this case.
What is the pH of 0.0001M aqueous solution of hcl?
The pH of a 0.0001M aqueous solution of HCl is 4. The pH of a solution is calculated using the formula pH = -log[H+], where [H+] is the concentration of hydrogen ions in the solution.

What is the percentage concentration of a 0.1N HCl solution?
A 0.1N (Normal) HCl solution is equivalent to a 0.1M (Molar) concentration of HCl. This means that there is 0.1 moles of HCl per liter of solution. So, the percentage concentration of a 0.1N HCl solution would be 0.1%.
What has a pH of 1 and completely ionizes in aqueous solution?
A strong acid, such as hydrochloric acid (HCl), has a pH of 1 and completely ionizes in aqueous solution, meaning all molecules dissociate into their constituent ions. This leads to a high concentration of hydrogen ions (H+) in the solution, resulting in the low pH value.
What is hydrochloric acid in aqueous solution?
This is a solution of hydrogen chloride (HCl) in water.
Explain why a 0.10 HCL solution is assumed to have a pH value 1?
HCl is a strong acid. Therefore, it can be expected to fully dissociate in aqueous solution, yielding one hydrogen ion and one chloride ion per molecule. The concentration of the hydrogen ion should thus be the same as the initial concentration of the HCl. Therefore, a 0.10M HCl solution has an H+ concentration of 0.10M. By the equation pH=-log[H+], the pH of this solution is 1.
Is HCL acidic in aqueous solution?
Yes, hydrochloric acid (HCl) is acidic in aqueous solution. It dissociates into H+ and Cl- ions in water, resulting in the release of hydrogen ions that make the solution acidic. It has a pH lower than 7.
What is lab normality of hcl?
The normality of a solution is a measure of the concentration of a solute in a solution. For HCl (hydrochloric acid), the normality would depend on the concentration of the HCl solution. For example, a 1 M (molar) solution of HCl would be 1 N (normal).
Standardization of Hcl using Borax?
You can standardize a hydrochloric acid (HCl) solution using borax (sodium borate) by titrating a known concentration of HCl with a solution of borax. The reaction between HCl and borax can be used to determine the exact concentration of the HCl solution. By accurately measuring the volume of the titrant and using stoichiometry, you can calculate the concentration of the HCl solution.
