Question
LAB 2 REVIEW Anatomy and Physiology Upon adding acid to the buffer, the following chemical reaction t HCI (aq)+ NaHCO, (s)- H,O U)+ CO, (g)+ NaCI (aq) 3. Why did the buffer bubble or fizz? 4. What happened to the HCI when you added it to the buffer? 5. Why did the pH change less on the buffer side versus the water? 6. If your pH paper in dish 2 continued to remain the same color, push the system's limit further by adding, 30, 35, 40, etc., drops of HCl. Continue to test the buffer's pH until you see a dramatic change. Why do you think the buffer suddenly stopped buffering towards the end? 7. What can you conclude about the nature of buffers?Explanation / Answer
H+ + H2O-----------------------H3O+
4.When more HcL is added to buffer side then concentration of HCL is more as compared to NaHco3 so base cannot neutralize till end point and suddenly pH drops.
5.Buffer resist any change in pH till saturation .
