1. Knowing that these 2 molecules are always floating in the air, hypothesize why your distilled water ( which indeed was pure when put in the container and therefore should have been pH 7), instead had a pH between 5 and 6 (i.e. acidic, not neutral). 2. Hypothesize why the addition of sucrose did not change the pH of distilled water ( a big hint to the answer is in the lab section on Acids & Bases).

Four times which then shuts before gravity can pull the water back down. w cats to drink in this fashion, including how water's molecular structure contributes to the process. e appropriate blanks in the sentences on the right. Terms can be used once, more than once, or not at all. Reset Help Water molecules stay close to each other as a result of existence of hydrogen bonds. Collectively, hydrogen bonds hold the substance together, this phenomenon is called cohesion The clinging of one substance to another, which is called adhesion also plays a role. In this way, adhesion of water tırough hydrogen bonds to the molecules, which comprise the villi on the cat's tongue, helps counter the downward pull of gravity. As a result, such a phenomenon as adhesion helps drops of water stay whole and attached to each other. At the same time, cohesion allows drops to be transported…
