WebpOH and Concentration in Bases The pOH scale is essentially the pH scale, but backwards. This is shown in the following image: On the pOH scale, all bases are below 7. A strong base would be between 1 and 3, while a weak base would be between 4 and 6. 7 is still neutral and above 7 is an acid. WebA buffer is an aqueous solution containing a weak acid and its conjugate base or a weak base and its conjugate acid. A buffer’s pH changes very little when a small amount of strong acid or base is added to it. It is used to prevent any change in the pH of a solution, regardless of solute.

Web- [Instructor] A strong acid is an acid that ionizes 100% in solution. For example, hydrochloric acid, HCl, as a strong acid it donates a proton to water, H2O, to form the hydronium ion, H3O plus, and the conjugate base to HCl which is the chloride anion, Cl minus.
