Learn ionic equilibria test MCQs: ph of buffer solution depends upon concentration of, with choices acid (h ), conjugate base (oh), salt, and both a and b for online bachelor degree. Practice merit scholarships assessment test, online learning buffer solutions quiz questions
pH 8. 54. Note: Every problem involving titration and buffers is similar to the sample problem just given. The addition of strong base (or acid) affects the initial concentrations of HA and A. The pH can then be determined using the appropriate class 1, 2, or 3 solutions.
pH calculation questions pH of buffer solution. Calculate pH of solution prepared from 0. 1 mole of formic acid and 0. 02 mole of NaOH diluted to 1L. pK a 3. 75. This is classic buffer question that we will solve using HendersonHasselbalch equation.
Apr 11, 2014 Calculate the pH of a buffer solution made from 0. 20 molL HCHO and 0. 50 molL CHO. The acid dissociation constant of HCHO is 1. 8 10. Solution. Plug the values into the HendersonHasselbalch equation for a weak acid and its conjugate base. HA HO HO A pH# pKa log(([A)([HA))#
