WebJul 9, 2014 · To calculate the pH of HCl you need to know the concentration expressed in molarity (mol HCl/L solution). You will use the following equation to find the pH. pH = -log[H+] This means you take the negative log of the hydrogen ion concentration to find the pH. The hydrogen ion concentration is the same as the concentration of the acid because … WebGiven [H +] = 4.1 x 10 -4 M, find the following: We have the concentration and will attempt to find: pH. pOH. [OH–] To find the pH we will use the following formula using the given acid concentration: pH = – log (4.1 x 10 -4 M) Note: The number of sig figs will be the number of decimal places pH and pOH should be rounded to. Answer: pH = 3.39.

WebApr 11, 2015 · pH = -log (hydrogen ion activity). and "pH of 7.6 M HCl is about -1.85 (not -0.88)" So how far off is -log (5) = -0.69 from the real answer? From this table of activity coefficients 5m HCl has an activity coefficient of 2.38, so activity is 11.9, which yields pH = … WebThe pH of a solution is therefore defined as shown here, where [H 3 O +] is the molar concentration of hydronium ion in the solution: pH = − log[H3O +] Rearranging this equation to isolate the hydronium ion molarity yields the equivalent expression: [H3O +] = 10 − pH Likewise, the hydroxide ion molarity may be expressed as a p-function, or pOH:

WebMay 13, 2016 · Explanation: The pH of a given solution is determined using the following formula: pH = −log[H 3O+] To find the [H 3O+] the formula must be manipulated as follows: log[H 3O+] = − pH. [H 3O+] = 10−pH. Plugging the value of the pH in the equation gives: [H 3O+] = 10−5.6. [H 3O+] = 100.4 ⋅ 10−6.
