What is the concentration of HCl if it makes a solution in water of pH 1.5?

Since pH=-log[H+], then [H+]=10-pH
10-1.5=.0316
And since HCl is a strong monoprotic acid, the [H+]=[HCl]
So the concentration is approximately 0.0316M

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%.
A solution containing 3.76 g naoh in 361 ml water is titrated with 491 ml hcl what is the concentration of hcl in the original solution?
Given that the amount of NaOH is known, and the volume of HCl required for titration can be measured, you can calculate the concentration of HCl by using the balanced chemical equation and stoichiometry. The concentration of HCl in the original solution can be determined by dividing the moles of NaOH used in the reaction by the volume of HCl used. This calculation will yield the molarity of HCl in the original solution.
How much concentration HCl in HCl fuming 36 percent?
About 13M. You can assume it is 13M if you don't need an exact concentration (like if you need a ~1M HCl solution for an extraction or whatever) but if you need an exact concentration (for a titration, for example) then you will need to standardize your HCl first.
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.
Does HCl change in concentration when neutralized with NaOH?
Yes, when HCl is neutralized with NaOH, the concentration of HCl decreases as it reacts with NaOH to form water and NaCl. The concentration of the resulting NaCl solution will increase as the reaction progresses.

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).
Calculate the concentration of OH- in a HCL solution where hydrogen concentration is 1.3M?
In a solution of HCl, all of the HCl molecules ionize completely in water to form H+ and Cl- ions. Therefore, the concentration of OH- ions in a HCl solution is negligible since there are no OH- ions produced in the dissociation of HCl.
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.
Standardization of hcl solution with primary standard na2co3 solution?
To standardize an HCl solution with a primary standard Na2CO3 solution, first, prepare a Na2CO3 solution of known concentration. Then, titrate the Na2CO3 solution with the HCl solution using a suitable indicator until the equivalence point is reached. From the volume of HCl solution used and the known concentration of Na2CO3, you can calculate the exact concentration of the HCl solution.
How do you prepare hcl 0.02n?
To prepare 0.02N HCl solution, you would need to dilute a more concentrated HCl solution with water. Calculate the volume of concentrated HCl needed using the formula C1V1 = C2V2, where C1 is the concentration of the concentrated HCl, V1 is the volume needed, and C2 is the desired concentration (0.02N). Dilute the calculated volume of concentrated HCl with water to reach the desired final volume.
What makes HCl an acid?
HCl is an acid because it donates hydrogen ions (H+) when dissolved in water. This donation of protons makes the solution acidic, as it increases the concentration of positively charged hydrogen ions. Acids like HCl have a pH below 7 and react with bases to form salts and water.
Why do you need to standardize HCl solution?
Standardizing an HCl solution is necessary to accurately determine its concentration. By titrating the HCl solution against a known standard solution (e.g., NaOH), you can calculate the exact concentration of the HCl solution. This ensures that your experimental results and subsequent calculations are reliable and reproducible.
