To calculate the pH of a weak acid, it is important to note that pH has no units, thus it is required to define it with H+ ion concentration.
Buffer solutions are the solutions in which the pH of the solution does not change on the addition of small amounts of acids or bases. Acidic buffer solutions are the solutions which contain a mixture of a weak acid and its salt with a strong base. ...
A strong acid is one that readily gives up its protons, and does so even when the ambient pH is low, which means there are already a lot of protons floating around. Weak acids do not give up their protons so easily, becoming dissociated to a meaningful extent only when pH is closer to...
Calculate the pH of a 0.0190 M solution of {eq}H_2S {/eq}. Weak Diprotic Acid: A monoprotic Arrhenius acid has a single dissociation equilibrium in aqueous solution, whose strength is described by a dissociation constant {eq}\rm K_a {/eq}. If {eq}\rm K_a < 1 {/eq}, then the...
Weak Acid: The concentration of the ions formed in the reaction after dissolving a salt of weak acid in the solution can be determined by using the acid dissociation constant value and its appropriate equilibrium constant expression. Answer and Explanation: We are ...
<p>To calculate the pH of a solution containing 100 mL of 0.1 M HCl and 9.9 mL of 1.0 M NaOH, we will follow these steps:</p><p><strong>Step 1: Calculate the moles of HCl and NaOH</strong> - <strong>Moles of HCl</strong> = Molarity × Volume (in liters)

Unfortunately your other approach (the one with pH 10.44) is wrong. You should use ICE table. Besides, it is obvious that something is wrong even without checking calculations. pH 10.44 means solution is basic, and you have solution of protonated nicotine, that is weak acid, its pH must be...
