In this step, you will create a model solution of pH = 6 with more Htions than OH ions. The black beans will
represent H* ions and white navy beans will represent OH-ions. Click or tap the bag of black beans to add 100 of
the beans to the beaker.

Tafari worked one summer on a ship that set weather buoys in the ocean. he watched how one of the buoys moved in the water. describe which parts of the wave would cause the buoy to bob up and down. which wave property determined how fast the buoys bobbed in the water? he observed that when the wind blew harder, the ocean waves were larger, and the buoys moved away from the ship. what effect, if any, did the waves have on how far the buoys moved? explain your answer.
