WebDec 16, 2024 · • The relative strength of weak acids are deduced from the Ka values. • Strong acids have higher Ka (lower pKa) values than weaker acids. Example ; Methanoic acid (HCOOH); Ka = 1.6 × 10−4 mol 𝑑𝑚−3 pKa = 3.8 Is a stronger acid than ethanoic acid (C𝐻3COOH); Ka = 1.7 × 10−5 mol𝑑𝑚−3 pKa = 4.8 16. WebSep 27, 2024 · Because HC 2 H 3 O 2 is a weak acid. Any chance a weak acid has to form, it will (the same with a weak base). As some C 2 H 3 O 2 − ions hydrolyze with H 2 O to make the molecular weak acid, OH − ions are produced. OH − ions make solutions basic. Thus NaC 2 H 3 O 2 solutions are slightly basic, so such a salt is called a basic salt.
