Strong Acids

How do we know if something's a strong acid/base?

From what I remember from 14a,
Strong acids include: HCl, HNO3, H2SO4, HBr, HI, HClO4
Strong bases are mostly bases that include OH in the chemical formula (ex: NaOH, KOH)

We know something is a strong acid or base if it fully dissociates in water.
Some common strong acids are:
HCl4, HCl, HBr, HI, HNO3, H2SO4
Some common strong bases are :
LiOH, NaOH, KOH, Ca(OH)2, Sr(OH)2, Br(OH)2

Best way is to memorize the strong acids. But a strong acid completely dissociates in a solution so that's another way to tell a difference.

It's also helpful to know that the problem will most likely give you the Ka and Kb of weak acids and bases, so if they're not given, the acid/base is most likely strong.

You need to memorize the strong acids (there are only a few) and strong bases are elements in the first 2 columns and OH

Since strong acids dissociate completely, a Ka value is usually not given.
