WebNov 20, 2013 · p H + p N H X 2 = − log k a m ≃ 33 ( − 50 ∘ C) ( ( a m) stands for a substance solvated by ammonia). Hence, in liquid ammonia at − 50 ∘ C, the pH scale can easily go all the way from 0 to 33 (of course, it can go a little lower and higher still, but again now activities become important), and that neutral pH is actually 16.5. WebNov 25, 2024 · I calculated the molarity of the conjugate base: [ClO -] = 0.1mol/0.2L = 0.5M. Then I applied the Henderson-Hesselbalch equation: pH = pKa + log ( [ClO - ]/ [HClO]) = …

Calculate the pH and the pOH of each of the following solutions at 25 ÅãC for which the substances ionize completely: (a) 0.000259 M HClO4 (b) 0.21 M NaOH (c) 0.000071 M Ba (OH)2 (d) 2.5 M KOH 2. Calculate the ionization constant for each of the following acids or bases from the ionization constant of its conjugate base or conjugate acid: (a) F− WebNov 13, 2016 · So far, we thus have that pH varies as follows when these are placed into solution: Sr(OH)2(aq) > NaOH(aq) >? >? > HBr(aq) We now know that HBrO is a weak acid, so it must dissociate less than HBr, meaning that it decreases the pH by less from about 7. That means the pH of HBrO(aq) > pH of HBr(aq). Now we have:
