strong vs weak acids

[Shreya Tamatam 3B]

How do you determine whether an acid is strong or weak?

[Nicholas Carpo 1L]

You can determine relative acid strength based on two main factors:
1. bond length in relation to the acidic proton (longer bond, stronger acid)
2. resulting anion stability (more stable conjugate base, stronger acid)

But to differentiate strong acids vs weak acids, usually you have to just memorize the strong acids.
HCL, HBr, HI, HNO3, HClO3, HClO4 and H2SO4

Electronegativity is also a factor to consider!

[Chloe Likwong 2K]

Strong bases usually have (OH-) in the compound.

[Andrew Bennecke]

Aside from memorizing the several strong acids and patterns for strong bases, learning the different trends of the acids with a halogen and strength of a H atom in a H-bond can also help decide which molecule is more acidic or more basic when given two to compare.

[Rebecca Park]

There is a table in the textbook that is nicely organized, but for binary, the more polar, the stronger the acid and the more weaker the H-A bond, the stronger the acid.
For Oxoacids, the greater the number of Oxygen atoms attached to the central atom gives a stronger acid. If it has the same number of O atoms, then you use electronegativity.
