14.9: The pH and pOH Scales: Ways to Express Acidity and Basicity

WebSep 30, 2024 · The pH scale shows how acidic or basic a chemical is in aqueous solution (mixed with water). The scale funs from 0 (most acidic) to 14 (most alkaline or basic), where 7 is neutral pH. Chemicals with pH values from 0 up to 7 are acids, those with a pH value of 7 are neutral, and those with pH values greater than 7 up to 14 are bases. WebAug 10, 2024 · To convert pH into [ H 3 O +] we solve Equation 14.9.1 for [ H 3 O +]. This involves taking the antilog (or inverse log) of the negative value of pH .

The ionization constant for water ( Kw) is 9.614 × 10 −14 at 60 °C. Calculate [H3O+] [ H 3 O +], [OH−] [ OH −], pH, and pOH for pure water at 60 °C. WebMar 6, 2014 · The molarity becomes the [H+] concentration of 3.2 × 10−3. We know this is the [H+] concentration because HNO3 is a strong acid, since the acid will completely dissociate into H+ and NO− 3. To find the pH calculate −log[H+] −log[3.2 × 10−3] = 2.49 = pH. To find the pOH take the pH value and subtract it from 14. 14 −2.49 = 11.51 = pOH.
