pH 4.o

Here is the completely rewritten code based on your request. ### **Changes in this version:** 1. **Layout Flipped:** The **Editable Data Table** is now placed **above** the Graph. 2. **Live Editing:** I removed the "Update" button. The graph now updates **instantly** as you type new numbers into the table. 3. **Scrollable Table:** The table is kept in a scrollable window (max height 250px) so it doesn't push the graph off the screen, but you can still access all data points. Save the following code as an `.html` file. ```html

Volume NaOH (mL)	pH Value

Experiment Analysis:
Plotting pH vs. Volume reveals the dissociation constants ($K_1, K_2$).

• First Equivalence Point: Occurs around 30 mL (pH ~5.3 to 6.0).
• Second Equivalence Point: Occurs around 52 mL (pH ~8.6 to 10.0).

Tip: Type new values in the table above to test how data errors affect the curve.
