Solved QUESTION 21 . 1 POINT The pOH of a solution is equal

Webb5 aug. 2024 · Answer: pOH = 9.88. Explanation: pH or pOH is the measure of acidity or alkalinity of a solution. pH is calculated by taking negative logarithm of hydrogen ion … 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. ionic bonding starter

The acid and titrant are both monoprotic and the sample and titrant solutions are equally concentrated; thus, ... pOH = −log (5.3 × 10 − 6) = 5.28 ... 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. ontario shared services ontarioWebb14 What is the pOH of a solution when H is 904 10 13 M 15 What is the pOH of a from SCIENCE 128 at Grandview High School.
