Question

What is the concentration of H+ ions at a pH = 2? mol/L What is the concentration of OH– ions at a pH = 2? mol/L What is the ratio of H+ ions to OH– ions at a pH = 2? : 1

Answer 1

Answer:

In Step 5, you will calculate H+/OH– ratios for more extreme pH solutions. Find the concentration of H+ ions to OH– ions listed in Table B of your Student Guide for a solution at a pH = 2. Then divide the H+ concentration by the OH– concentration. Record these concentrations and ratio in Table C.

What is the concentration of H+ ions at a pH = 2?

0.01   mol/L  

What is the concentration of OH– ions at a pH = 2?

0.000000000001   mol/L  

What is the ratio of H+ ions to OH– ions at a pH = 2?

10,000,000,000 : 1
