- Figure 2.12 A pH scale. Here, red dots signify hydrogen ions (H+) and blue dots signify hydroxyl ions (OH). Also shown are the approximate pH values for some common solutions. This pH scale ranges from 0 (most acidic) to 14 (most basic). A change of one unit on the scale corresponds to a tenfold change in the amount of H+ ions. Photos, JupiterImages Corporation. Figure It Out: What is the approximate pH of cola?arrow_forwardManufacturers make carbonated drinks by forcing pressurized carbon dioxide gas into flavored water. A chemical reaction between water molecules and some of the CO2 molecules creates hydrogen ions (H+) and bicarbonate, which is a buffer. In your opinion, is this reaction likely to raise the pH of a soda above 7, or lower it? Give your reasoning.arrow_forwardThe “octet rule” in chemistry helps predict the types of bonds thatatoms will form. In general, an atom will be most stable if it fills itsouter shell of 8 electrons. Atoms with fewer than 4 valence electronstend to donate electrons and those with more than 4 valence electronstend to accept additional electrons; those with exactly 4 can do both.Using this rule, determine what category each of the followingelements falls into: N, S, C, P, O, H, Ca, Fe, and Mg. (You will needto work out the valence of the atoms.)arrow_forward
