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
