Hello, This is a matter I have been having some difficulties with for the past few days. My question: How is it that I would go about distinguishing molecular compounds in regards to their capacity to ionize and yield hydrogen ions when dissolved into distilled water? For example, if ethanol (C2H5OH) was dissolved into water, why couldn't the hydrogen atom in the compound ionize and result in the formation of an acid? Couldn't the -OH bond dissociate and result in the formation of a base? Similarly, why is it that methane (CH4) or sucrose (C12H22O11) cannot ionize and yield hydrogen ions? This may be common knowledge and I may have been merely mislead. However, I am enrolled in a high school program and I understand that at this level, a lot of details in the sciences are simply left out. I greatly appreciate any clarity or enlightenment anyone can offer me. Thank you, Eric.
