Consider two solutions: solution x has a ph of 4; solution y has a ph of 7. from this information, we can reasonably conclude that consider two solutions: solution x has a ph of 4; solution y has a ph of 7. from this information, we can reasonably conclude that the concentration of hydrogen ions in solution y is 1000 times as great as the concentration of hydrogen ions in solution x the concentration of hydrogen ions in solution x is 1000 times as great as the concentration of hydrogen ions in solution y solution y has no free hydrogen ions (h+) the concentration of hydrogen ions in solution x is 3 times as great as the concentration of hydrogen ions in solution y

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
