WebAnswer (1 of 4): For the purposes of answering the question, all you need to know is the following equation: pH + pOH = 14 And then, given the data in the question pOH = 14-pH pOH = 14–4.5 pOH = 9.5 However, compounds do not have pH. pH is the hydrogen ion concentration in water. Addition of... WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14. Anything below 7.0 is acidic, and anything above 7.0 is alkaline, or basic. Image modified from " Water: Figure 7 ," by OpenStax College, Biology, CC BY 4.0. Modification of work by Edward Stevens.
