The Bullshit Part Of Chp 12 Flashcards
1
Q
How to calculate Ksp?
A
*Get M then square it among aqueous products
2
Q
How to calculate whether a precipitate forms?
A
- get the insoluble one
- Get the M of both
- Use the Eq bullshit equation
- compare it to Ksp
3
Q
What to do when an ion is put into a bath that has the same ion?
A
- use the ICE table and have that ion as a finite initial M
- +s on aq part
- solve for whatever the fuck you need
4
Q
How to identify a conjugate acid-base thing?
A
- acid has one more H on the aq side
* Base has one less H on aq side
5
Q
Formula for pH?
A
pH = –log[H+]
6
Q
How to calculate pH of a weak acid?
A
- theres an initial M in big compound
* subtract x from that and add to others
7
Q
What is new Eq for ΔG
A
- ΔG = ΔGi + RTln(Q)
* q is reaction quotient
8
Q
When delta G is at Eq (ΔGi = -RTln(K)) what happen with different signs?
A
*ln(K) + and G (–)
K > 1
*vice fucking versa
9
Q
How to tell if there’s a precipitate in an aqueous solution?
A
*Q>Ksp - precipitate
