WebbThe strategy here is to calculate the pOH and then, using the pH + pOH = 14 relationship, determine the pH. NaOH is a strong base, so [OH –] = [NaOH], and therefore, the pOH is: pOH = -log 0.850 = 0.0706 The pH then is equal to: pH = 14 – pOH = 14 – 0.0706 = 13.9 As expected, the pH is very high because it is a solution of a strong base.

WebbpH & pOH, often denoted by an alphabet H + & OH-respectively, is the measure of hydrogen & hydroxide ion concentration of the solution. pH is an important factor in chemical process, represents the acid & alkalin … WebbNotice, since we have two significant figures for the concentration, we need two decimal places for our pOH. So to find the pH, we know that pH plus pOH is equal to 14.00 at 25 degrees Celsius. So we can plug in the pOH of 2.70, and that gives us pH plus 2.70 is equal to 14.00. So the pH of the solution is equal to 11.30.

Webb29 aug. 2014 · Solve for pOH. pOH = 14 - pH pOH = 14 - 1.5 = 12.5 When the pOH is solved, solve for the concentration by using log. pOH = -log[OH-] 12.5 = -log[OH-]-12.5 = log[OH-] … WebbThe pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution.
