Plot the graph

The graph of a silver halide titration curve.

The spreadsheet for the silver iodide titration curve is as follows:

The graph of the silver halide titration curve looks like this:

As the solubility product of halides declines, so does the solubility of halides. Silver iodide has the steepest slope, indicating that it is least soluble. Because is dependent on the concentration of silver ions, the values rise as the solubility product decreases.
