pH COMPARISON OF BUFFERED & UNBUFFERED SOLUTION (1 of 3)<br />
Initial pH<br />
(left) Unbuffered solution =4.8 and is 1.78x10-5M HCl (weak acid). (right) Buffered solution =4.8 and contains >.101M CH3COOH & .099M CH3COONa. Buffer solutions resist change in hydrogen ion concentration. Indicator is bromocresol green.
