Acids

[Emma Scholes 1L]

How can you tell what is a weak acid vs. what is a strong acid?

[Dimitri Speron 1C]

A strong acid dissociates completely in water, or at least so much that it is practically completely. Mathematically, this means that the Ka (acidity constant) is infinitely large. For weak acids the acidity constant will be less that 10^-3. This means that not all of the acid is dissociating in water, as such the concentration of hydronium does not increase as much as it does for a strong acid. The exact same stuff is all true for bases as well.

A weak acid does not fully dissociate in water and therefore, would require an equilibrium equation. A strong acid fully dissociates in water and so it would be written as just a forward reaction. You just have to memorize the strong acids and every other acid is a weak acid. The strong acids are HCl, HNO3, H2SO4, HBr, HI, HClO4, HClO3.

A weak acid or base does not dissociate fully while a strong acid or base does indeed dissociate fully ion the solution.

Strong acids and bases disassociate/ionize completely while weak acids and bases do not completely. this is the main difference.

What are some strong bases that we should know of?

[Erin Kim 2G]

The strong acids include HCl, HNO3, H2SO4, HBr, HI, HClO4, and HClO3.
The strong bases include LiOH, NaOH, KOH, RbOH, CsOH, Ca(OH)2, Sr(OH)2, and Ba(OH)2.
