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. WebAnd solving for the pH, we get that the pH is equal to 9.25. So we have the pH and our goal is to solve for the concentration of hydronium ions, and pH is equal to the negative log of the concentration of hydronium ions. So we can plug our pH right into this equation.

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. 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:
