pH = -log[H+]
That is, the pH of a solution is the negative log of the concentration of hydrogen atoms. The concentration of hydrogen atoms must be in units of Molarity, or moles per liter. In order to determine the pH of a solution containing 1 mole of HCl, you must also know the volume of the solution.
I am assuming the question is: What is the pH of 1M HCl, and not 1 mole. 1 mole HCl is simply the mass in grams of the atomic weight of H and Cl: 1+35.45=36.45. This is not a unit of concentration and if that is truly the question then the answer is undefined.
Molarity on the other hand, and other units of concentration, are completely independent of total amount of solution (volume or mass): molarity (M)= moles/Liters
HCl is a strong acid. This means that all of those acid hydrogens are releasing into solution and therefore the calculation is very simple:
pH of strong acid= -log[H+] 1M HCl= 1M[H+] + 1M[Cl-] pH=-log[1]= 0
The pH of a 0.1 M HCl solution is 1. HCl is a strong acid that completely dissociates in water to form H+ ions. Thus, the concentration of H+ ions in a 0.1 M HCl solution is 0.1 M, resulting in a pH of 1.
Find moles HCl. 5 g HCl (1 mole HCl/36.450 grams) = 0.1372 moles HCl Now, Molarity = moles of solute/Liters of solution Molarity = 0.1372 moles HCl/1 liter = 0.1372 M HCl Then. -log(0.1372 M HCl) = 0.9 pH ( you might call it 1, but pH can be off the scale ) -----------
When HCl dissociates, it produces 1 mole of H+ ions and 1 mole of Cl- ions for every mole of HCl. So, 1 mole of HCl will produce a total of 2 moles of ions (H+ and Cl-).
In 1 Litre solution there are:1.0 mole HCl (totally ionised into 1.0 mole H3O+ and 1.0 mole Cl-)and54 mole H2O (the remaining of 55)
These chemicals react in a direct proportion of one to one, measured in moles of course, not by weight. A mole of NaOH weighs more than a mole of HCl.
pH=1 means the solution contains 0.1 mole per liter H+ ions. Strong acids like hydrochloric acid (HCl) or sulfuric acid (H2SO4) dissociate completely in water so 0.1 mole of HCl (= 3,65 g per liter) has a pH=1. For sulfuric acid 0.1 mole = 9.8 g per liter give pH =1
The pH of a 0.1 M HCl solution is 1. HCl is a strong acid that completely dissociates in water to form H+ ions. Thus, the concentration of H+ ions in a 0.1 M HCl solution is 0.1 M, resulting in a pH of 1.
Find moles HCl. 5 g HCl (1 mole HCl/36.450 grams) = 0.1372 moles HCl Now, Molarity = moles of solute/Liters of solution Molarity = 0.1372 moles HCl/1 liter = 0.1372 M HCl Then. -log(0.1372 M HCl) = 0.9 pH ( you might call it 1, but pH can be off the scale ) -----------
When HCl dissociates, it produces 1 mole of H+ ions and 1 mole of Cl- ions for every mole of HCl. So, 1 mole of HCl will produce a total of 2 moles of ions (H+ and Cl-).

In solution with a pH of 1 [H+] is 0.1M. Since HCl is a strong acid [HCl] will also be 0.1M. So, in 1 liter of solution you will have 0.1 mol of HCl.
The normality factor (NF) of HCl is 1, as it provides 1 equivalent of H+ ions per mole of HCl in a reaction.
or at least what's the formula to find the pH?
100 Liters? I will assume as much. Molarity = moles of solute/Liters of solution Molarity = 0.10 mole HCl/100.0 Liters = 0.001 M HCl -------------------------now, to find pH - log(0.001 M HCl) = 3 pH -----------------so, your acid is of 3 pH, which is to be expected at the volume od solution
.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 strong acid completely dissociates into an H+ ion and an anion. pH is defined as pH = -log(H+ concentration) So if you have 0.01 mole hydrochloric acid (HCl) per 1 mole solution, since each mole HCl contributes a mole of H+ and a mole of Cl- then you would have H+ concentration of 0.01 pH = -log(0.01) = -(-2) = 2, so the pH = 2 Note that higher H+ concentrations result in lower pH number
