is CH3CO2H+NaOH->NaCH3CO2+H2O a reversible reaction, or is it just one way.

do you know if these react?
NaCH3CO2(s)+H2O(l)
if so, what are the products?

1) Should dissolve (doubt its a reaction). The crystals are just undissolved Sodium Acetate.

2) Lead Iodide precipitates, for it is insoluble in water. Lead Iodide is yellow, thus explaining your colour.

Get a anion/cation solubility data sheet, and study it. Saves you lots of time, especially in tests/exams. :)

Emkalon, did you edit and change your whole post because cyclonite4's reply doesn't make any sense (about the lead iodide). As for your answer, the reaction of sodium hydroxide with acetic acid as any reaction of a strong base reacting with (in this case) a noticeable acid goes to completion, so technically it should all be products. But there is some acetic acid in solution, less and less with rising pH though. Really though dissolving sodium acetate in water will lead to a solution of sodium acetate which will be slightly basic due to:

CH3COO- + H2O ---> CH3COOH + OH-

He must have changed his post.
Makes me look like a mild TGC :(

He had 2 rxns:
1) NaCH3COO + H2O.
2) KI + PbCH3COO.

TCG ?
Thymine, cytosine and guanine. Hope the adenine is OK.

TGC is an acronym for a defective gene, known as 'The_Gender_Changer'. :D

Surely you know of him?
