Look at Figure 2.17. If you did this titration using TRIS instead of phosphate, how would the titration curve look compared to the figure? Explain.

Figure 2.17 Buffering. Acid is added to the two beakers on the left. The pH of unbuffered H₂O drops dramatically while that of the buffer remains stable. Base is added to the two beakers on the right. The pH of the unbuffered water rises drastically while that of the buffer remains stable. 20 Unbuffered H₂O Buffer pH 7.0 Add 1 mL 0.1 MHCI pH much lower 201 pH stable with buffer Unbuffered H₂O pH meter pH much higher Buffer pH 7.0 Add 1 mL 0.1 M NaOH - Electrode pH stable with buffer
