Some kids are playing with a jump rope. They notice that they can make transverse waves when they shake the rope up and down. They shake it quickly and notice that the wave that forms appears to be holding still. What type of wave interaction is this?

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
