WebbAnswer (1 of 2): RbOH is a strong base which complete dissociates to give OH⁻ ions. Hence, [OH⁻] = [RbOH]ₒ = 1.0 × 10⁻³ M pOH = -log[OH⁻] = -log(1.0 × 10⁻³) = 3 pH = pKw - pH = 14 - 3 = 11 WebbThe pH of 10 −3 M solution of NaOH is 8176 65 Odisha JEE Odisha JEE 2010 Equilibrium Report Error A 3 B 11 C 4 D 12 Solution: [OH −] = 10−3M pOH=-log [OH −] = −log(10−3) = …
Webb1 juli 2016 · If you add 3 ⋅ 10 − 2 m o l N a O H to 1 L of 2 ⋅ 10 − 2 M A c O H you end up with a solution that contains 2 ⋅ 10 − 2 m o l L − 1 A c O X − and 1 ⋅ 10 − 2 m o l L − 1 O H X −. So the pH is 12. Share Improve this answer Follow edited Jul 22, 2024 at 10:33 A.K. 12.1k 7 43 93 answered Jun 30, 2016 at 18:45 aventurin 6,934 3 26 37 Add a comment 0

I started by converting everything to moles, writing out an equation for H A and O H X − reacting to make H X 2 O and A X −, getting 0.0985 mol of H A left after all the O H X − was used up, and 0.015 mol of A X − produced. At that point I got a bit stuck. norman wright mechanical brisbaneWebbGo through the simple and easy guidelines on how to measure pH value. Know the concentration of hydrogen ions in the solution. Calculate the pH by using the pH to H + formula i.e pH=-log [H +] You can also calculate the pOH and the concentration of hydroxide ions. The other way to know pOH is subtract 14 from pH value. norman yakeleya dene national chiefWebbCorrect option is A) NaOH dissociates as Na + and OH − in solution. Hence 0.3M of NaOH will give 0.3M of OH − ions. We know that pOH=−log[OH −] Thus, pOH=−log[0.3], since … norman wound care center
