WebBuffer Practice Questions. 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. WebHydrochloric acid, also known as muriatic acid, is an aqueous solution of hydrogen chloride with the chemical formula HCl (aq).It is a colorless solution with a distinctive pungent smell.

WebThe other way to know pOH is subtract 14 from pH value. Formula: pH is stated as the negative of the base ten logarithm of the molar concentration of hydrogen ions available in the solution. pH=-log([H +]) pOH=-log([OH-]) Relationship between pH and pOH is. pH+pOH=14. Example: Question1: Find the pH of a 0.0025 M HCl solution? Answer: Given … 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.
