Witryna12 wrz 2024 · A solution containing a mixture of an acid and its conjugate base, or of a base and its conjugate acid, is called a buffer solution. Unlike in the case of an acid, … Witryna27 lut 2024 · H + (aq) + CH 3 COO – (aq) → CH 3 COOH (aq). Since additional H + ions of acid are consumed (neutralized), the pH of the solution remains unchanged. This resistance to change in pH on the addition of a strong base is called as reserve basicity and is due to CH 3 COO – ions.. If strong base like NaOH is added to the buffer …
