ksp

what is solubility

M of a substance dissolved in an aq sol

solubility product

K calc for dissolving solid, solute

Bigger K means…

more dissolved

Steps to calc Ksp when given solublity

1. Write the formula

2. Ksp=[eq concentration of prod]

3. Ksp= coeffiecient sol

Steps to calc common Ion Effect (calc x in dif eq)

1. Find sol

2. Write eq using any given sol

3. Ksp = (given + x)(coeffiecient x)

how to find most sol

solve for x by foiling out eq

what happens when states/temp increases

more gaseous = more entropy/delta s

entropy depends on

1. particles

2. states

3. complexity

—H and + S =

both spon

—H and —S =

L - spon

H - nonspon

+H and +S =

L - nonspon

H - spon

+ H and —S =

both nonspon

to determine temp of spon what eq is used

deltaG = deltaH - TdeltaS

how to calc g in non std condos

Grxn + RTln(prod/react)

K>1

rxn spon fwd

K<1

rxn non spon fwd

K=1
