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. Buffer solutions are used as a means of keeping pH at a ... WebA 1 litre solution containing NH4Cl and NH4OH has hydroxide ion concentration of 10–6 mol/lit. ... 19.
