16.6: Finding the [H3O+] and pH of Strong and Weak Acid Solutions

WebbHCl is virtually complete, and the equilibrium lies completely to the right, therefore, the concentration of the acid equals the concentration of hydronium ions produced. For instance, a 0.01 M HCl solution will completely dissociate into 0.01 M H3O + and 0.01 M Cl-. The effective concentration of HCl after "equilibrium" has been reached will ... WebbAll right, so the concentration of HCl in our original solution would be, we had 0.000844 moles. All right, divide that by liters. That was 0.0200 liters, right? 20 milliliters is equal to 0.0200 liters. And so we can do our calculation here. So we can take 0.000844, and we can divide that by 0.0200, and we get for our answer here 0.0422 molar.

Solutions with a pH below 7.0 are acidic while solutions with a pH above 7.0 are basic (or alkaline). Since the pH scale is logarithmic, not linear, a solution of pH 1 would have ten times (not twice) the [H+] that a solution of pH 2.

WebbpH of any acid can be calculated by using the following formula: pH= -log (H+) Here H+ refers to the concentration of H+ ions or the Hydronium ions. Here it can be clearly observed that 1 moles of sulphuric acid gives rise to 2 moles of H+ ions. Therefore, 0.01 moles of H2SO4 will give rise to 0.02 moles of H+ ions. WebbThe pH of ~0.002 mol of H3O+ ions = 1.698 (rough rounding, but lower pH value...) Is it correct to say then that because the incremental H3O+ mols are so negligent, we overlook these moles as well as the (ever smaller) products from continued reactions that will lead to additional H3O+ moles?
