What is the concentration of H+ ions at a pH = 2? mol/L
In Step 5, you will calculate HOH 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 Ht concentration by
the OH concentration. Record these concentrations and
ratio in Table C.
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?

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
