Introduction to pH: pA, pB, A and B

When you press "New Problem" a value will appear in one of the cells in the table. You must properly fill in the other three windows. Pressing "Cheack Answer" checks your answer and returns the result in the second table. If you get a problem incorrect, you should retry it until it is correct.

Hints

• Use TAB to move between cells
• Use "e" notation for scientific notation: 1.2*10^-3 would be entered 1.2e-3
• Pressing the "Show Answer" will cause the solution to appear and you will no longer be able submit an answer for that problem.
