This page is a drill and practice exercise in basic pH calculations. When
you press "New Problem" a value will appear in one of the windows. You must
properly fill in the other three windows. Pressing "Check Answer" does so and
returns the result in the second table. If you get a problem incorrect, you
should retry it until it is correct. Use the "e" notation to enter numbers
in scientific notation:
Hints
Use TAB to move between cells
1.2*10-3 would be entered 1.2e-3
If you miss a problem three times, pressing "Show Answer" will cause the correct answer set to be displayed. The original given value will be highlighted.
