Diagram of a weak acid

WebJun 26, 2024 · A weak acid only partially dissociates from its salt. The pH will rise normally at first, but as it reaches a zone where the solution seems to be buffered, the slope levels out. After this zone, the pH rises sharply through its equivalence point and levels out again like the strong acid/strong base reaction. WebScience Chemistry 2.2 6. (i) Define pH in words. The strong acid HClag has a pH value of 1, use the following equation for a strong acid: Cla HClaa and convert the following expression to deduce the hydrogen ion concentration: pH = -log10 [H+] Ha pH = + (ii) Use the above expression to deduce the pH of HCl (ag) given the concentration of the acid to be 4.5 …
