pH = 0.0 (zero)
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

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
