Calculating pH Values of Various Acid Solutions - Prof. Dale E. Wheeler, Quizzes of Chemistry

Appalachian State University (ASU)Chemistry
Prof. Dale E. Wheeler

A series of calculations for determining the ph values of various acid solutions based on their given concentrations and the ka (dissociation constant) of each acid. The acids include acetic acid, acrylic acid, alloxanic acid, anisic acid, ascorbic acid, cacodylic acid, cyanoacetic acid, dimethylmelonic acid, furoic acid, lactic acid, lutidinic acid, m-chlorobenzoic acid, o-aminobenzoic acid, o-iodobenzoic acid, and formic acid.
