What are the six strong acids

HCl, HBr, HI, HNO3, HClO4, H2SO4

Common ion effect

The shift in an ionic equilibrium caused by the addition of a solute that takes part in the equilibrium

Bronsted Lowry concept

Acids donate protons, bases accept protons

As temperature increases...

The value of Kw increases

Buffer

A buffer solution is one that controls pH. A buffer is made by combining a weak acid with strong base or visa versa.

Henderson hasselbach equation

PH=pka+log(base/acid)

Strong's acids have ___ dissociation

100%, small pka

Titration curves

PH=pka midpoint is where acid is identifiable. For a weak acid at equivalence point pH is basic

Weak acids have ___ dissocation

Less than 100%, strong HA

Solubility

Mass/L

Molar solubility

Moles/L

When Q>Ksp

Solution will precipitate out

What does K=

((H3O)(A))/(HA)

If [HB]/[B-]=.1

Pka=ph-1

If [HB]/[B-]=10

Pka=pH+1
