WebMay 15, 2024 · Ka = [0.3 2]2[α] Calculating for α, we get it as 5.33 × 10 − 19 And we get [H] as 0.15. ∴ pH = 0.8 Is my approach wrong??? Another approach: I have been told by my teacher that resultant pH will nearly be the pH of strong Acid but if we add Weak acid will it not dilute the strong acid. Here in this case make the volume twice. acid-base equilibrium WebThe pH scale measures a solution’s acidity or alkalinity. The range for the pH scale is 0 (strong acid) to 14 (strong alkali). pH 0 – 2: strong acid pH 3 – 6: weak acid pH...

The acid constant is defined by the relationship: Kc × 1 = Ka = [ H3O +][ A −] [ HA ]

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.
