WebSep 19, 2024 · To define the pH scale as a measure of acidity of a solution. Because of its amphoteric nature (i.e., acts as both an acid or a base), water does not always remain as H 2 O molecules. In fact, two water molecules react to form hydronium and hydroxide ions: (16.4.1) 2 H 2 O ( l) ⇌ H 3 O + ( a q) + O H − ( a q) This is also called the self ... WebThe pH scale measures how acidic an object is. Objects that are not very acidic are called basic. The scale has values ranging from zero (the most acidic) to 14 (the most basic). As …
