making of Lead(II)acetate trihydrate
Hello
I would like to make Lead(II)acetate trihydrate.
I have 100% GAA and lead oxide.
As I understand I must use 50% GAA, so I will mix it with water as 50:50. But how much should I pour of that GAA mix onto my lead oxide? And what is
the easier way to dry off the excessive wetness from the final product?
I also have lead hydroxide and lead acetate - I wanna turn these ones also to Lead(II)acetate trihydrate. I guess the % is different then when mixing
with GAA.
Big thanks for any suggestions.

PbO + 2 CH3COOH + 2H2O > Pb(CH3COO)2.3H2O
Likewise,
Pb(OH)2 + 2 CH3COOH + H2O > Pb(CH3COO)2.3H2O
Go to a periodic table and calculate the weight ratios of these reactions. Then multiply by the weight of reactants. Then mix. Then crystallize
and/or recrystallize.
Come on, gimme something harder.

As I'm bored,
MW Moles Amount
PbO 223.1994 1 223.1994
CH<sub>3</sub>COOH 60.05256 2 120.10512
H<sub>2</sub>O 18.01528 2 36.03056
379.33508
Pb(CH<sub>3</sub>COO)<sub>2</sub>.3H<sub>2</sub>O 3
79.33508
The hardest thing about that was the formatting. Why does the BB strip out all the spaces.
Mike.
