A student is investigating factors that might influence solubility. In one experiment, she places one sugar cube each into two different glasses of water at room temperature. She also places a third sugar cube into a third glass of water at a higher temperature. She notices that the cube in the water at the higher temperature dissolves more quickly. Which of the following statements was most likely the hypothesis she was testing?

Calculate the ratio of h+ ions to oh– ions at a ph = 7. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 7. are they the same? why or why not? record your comparison in table a. what is the concentration of h+ ions at a ph = 7? mol/l what is the concentration of oh– ions at a ph = 7? mol/l what is the ratio of h+ ions to oh– ions at a ph = 7? : 1
