WebThe first thing we would need to do is to find the acid and the conjugate acid. Then we’ll find the pKa values for those. We know that acid loses the proton in an acid-base reaction, so obviously the acetylene species on the left is our acid. And since the NH 2– accepted that proton, NH 3 is the conjugate acid. WebOct 25, 2024 · Ka ()—the acid dissociation constant—tells you the strength of an acid in a different and more specific way than the better-known pH.Because Ka produces extremely wide-ranging values, pKa ()—the negative logarithm (base 10) of Ka—is often used to simplify the range of acid strength values.If all of this is twisting your brain a little, here’s …
