WebbAlright, so let's go ahead and write our initial concentrations here. So our goal is to calculate the pH of our solution. And we're starting with .25 molar concentration of sodium acetate. And so that's the same concentration of our acetate anion, here, so we're gonna write: 0.25 molar, for the initial concentration of the acetate anion.

Webb3 feb. 2024 · The given 0.205 M ammonia is the total concentration for both forms of that species, the acid and the base, NH3 and NH4+. However, for a weak base like ammonia, we can assume that the amount of NH3 that has been changed to NH4+ is so low (by a magnitude 5x less than 10, given by the kb) that doing the calculation wouldn't change … Webb1 sep. 2011 · The estimated pH of the solution is 6.69 while the measured value is 6.44. Based upon the data in Table 2, the uncertainty for estimated pH has been determined to be ±0.3 pH units. Students would report their answer as 6.6 ±0.3.
