For Part 1 Mixing Ratios.
1. Plot average pH vs. ([conj. base]/[conj. acid]) AND plot a second graph: average pH vs.
log([conj. base]/[conj. acid]) for your data in Table 1. Effect of A/HA Mixing Ratio on pH.
For the second graph, report the trendline equation and R² in your lab notebook.
(Substitute the actual variables for "x" and "y" in the equation.).
