Explain why a buffer can be prepared from a mixture of NH 4 Cl and NaOH but not from NH 3 and NaOH. Explain why the pH does not change significantly when a small amount of an acid or a base is added to a solution that contains equal amounts of the acid H 3 PO 4 and a salt of its conjugate base NaH 2 PO 4. Solution.

WebSince the pH scale is logarithmic, not linear, a solution of pH 1 would have ten times (not twice) the [H+] that a solution of pH 2. Likewise, a solution of pH 12 would be 10 times more alkaline than a solution of pH 11. pH Calculations Involving HCl Solutions 1. Given the Wt% of an HCl solution, what is its theoretical pH value?
WebIt's somewhat contradictory to discuss pH as -log[H+], and then say that pH = -3.6 is possible. There is no way you can cram over 1000 moles of hydronium ions into a liter! The -3.6 value only makes sense if you explain that pH = - log (H+ activity), and that it is the deviation of activity from concentration that makes the value -3.6 possible. fluke etherscope series ii network assistantWebJul 8, 2014 · The hydrogen ion concentration is the same as the concentration of the acid because HCl is a strong acid and dissociates as follows: HCl -> H + + Cl− (notice the 1:1 … green father 比杰WebJan 30, 2024 · 0.00025 M HCl, HCl is a strong acid [H 3 O +] = 2.5 X 10 -4 M pH = -\log (2.5 X 10 -4) = 3.6 Then solve for the pOH: pH + pOH = 14 pOH = 14 - pH pOH = 14 - 3.6 = 10.4 3. … fluke etherscope service manual pdfWebWhat is the pH of a solution with a 2.4 × 10 ─4 M solution of HCl?
