What is the pH of an aqueous solution of HCl with a concentration of 42m?
the pH is .377 the pH is .377
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
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.
What is the pH of a 0.035 M solution of HCl?
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]
What is pH value of 1N HCl?
In 0.01 M of HCl, the concentration of the Hydronium ions is 0.01M as well since HCl is monoprotic. pH = -log [H3O+] = -log 0.01 = -log10-2 = -(-2log10) = 2 Thus, the pH of 0.01 M HCl is 2.

What pH would you get from dilute hydrochloric acid?
It solely depends on H+ concentration: each HCl gives one H+ , to calculate use pH = -log[H+] So, at [HCl]=1.0 >> pH= 0.0 at [HCl]=0.5 >> pH= 0.7 at [HCl]=0.1 >> pH= 1.0 at [HCl]=1.0*10-5 >> pH= 5.0 but don't ever use this simplified 'acid pH' calculus method when the answer comes close to (or exceeds) 6.5, 7 or 8 etc.
What is an example of an item with a Ph of 1?
hydrochloric acid HCl of a concentration higher than 0.1M
How to calculate pH of 1N HCl solution?
pH = -log10[H+], where [H+] is the hydrogen ion concentration. So, in this case, pH = -log10[1], yielding pH = 0.
What is normal pH of stomach?
The normal pH of the stomach is about 2-3 and is caused by a high concentration of HCl secreted by the parietal cells of the stomach.
What pH is HCL?
That is a very broad question. Because HCl is a strong acid, it's pH varies based on it's concentration. For example, a 12M solution has a pH of roughly -1.1. pH can in fact go negative when viewed from the standpoint of acid-base equilibrium.
How is the pH of the solution calculated?
The pH scale is a convenient method for expressing the hydronium ion concentration of a solution. pH = log(1/[H+]) = -log [H+]. [H+] is the hydronium ion concentration in M (molarity), which is the number of moles of solute per liter of solution.
What is the fix pH of HCL and HNO3?
The pH value of those solutions depends on the concentration and the temperature. Generally, solutions with higher concentrations of acids have lower pH values.
