Derive ostwald's dilution law for ch3cooh
WebThis is known as Oswald’s dilution law. And it can be applied to any dissociation constant, not just acid dissociation constants. For many weak acids, we can simplify Oswald’s dilution law even further. Many weak acids have a degree of dissociation that is very small. WebSep 8, 2024 · Let's take the example of a weak acid dissociation, to derive the dilution law. We'll start with an equation for the acid dissociation constant: Because a weak acid is a weak electrolyte, we know ...
