hi, my name Devin, i have an online class and this huge question is on my hw. i already tried my first attempt and i only have one more. can i get some help double-checking my work? and yes its Calculate the pH corresponding to each of the hydrogen ion concentrations given below, and indicate whether each solution is acidic or basic.(a) [H+ ] = 3.94 10-5M (b) [H+ ] = 9.55 10-8M (c) [H+ ] = 2.12 10-10M (d)...
± pH of a Strong Acid and a Strong Base pH is a logarithmic scale used to indicate the hydrogen ion concentration, [H+], of a solution: pH=−log[H+] Due to the autoionization of water, in any aqueous solution, the hydrogen ion concentration and the hydroxide ion concentration, [OH−], are related to each other by the Kw of water: Kw=[H+][OH−]=1.00×10−14 where 1.00×10−14 is the value at approximately 297 K. Based on this relation, the pH and pOHare also related to each other...
A. Hydrochloric Acid Solution and pH 1. Write the balanced chemical reaction for the dissociation of the hydrochloric acid. 2. Refer to the procedure for A to determine the concentrations of the solutions of hydrochloric acid. Remember to use MiV1-MV. Show work for trial 1. 3. Calculate the theoretical pH of each hydrochloric acid solution. Recall that hydrochloric acid is a strong acid, suggesting complete dissociation, so that the equation pH log (HO) can be used (equation 3). Show work...
With this how I calculate the Ammonia solutions pH and Ammonia Buffer solutions ph B. Preparation of Ammonia-Ammonium Buffer Solution Note that an ammonia buffer contains the conjugate base, ammonia, and its conjugate acid, the ammonium ion, NH typically added as NH,CI. Accordingly, the pk, value stated in Eq. (7) is that of the buffer's conjugate acid, NH.. For ammonia, pk, -log (1.8 x 107 4.74. (Note that the fact that the pk for NH, is the same value as...
