hi, i am trying to develop a lab where i find the solubility of Sodium acetate. I was wondering in i was in the right path.
We are given these three compounds:
Acetic acid aka vinegar
baking soda (sodium hydrogen carbonate)
So we are not given Sodium acetate so we have to first titrate NAOH with Acetic Acid which produces the sodium acetate and water. here is the equation.
Naoh + CH3COOH = CH3COONa + H2O
So i am going titrate acid(CH3COOH) to base (Naoh). How do i measure solubility of Acetic Acid( CH3COONa ) from that? check when it forms a precipitate?
The equation is
NaOH + CH3COOH ==> CH3COONa + H2O
Now, what is your question?
soorry i was writing the equation but computer went weird on me. So i titrate acid ( ch3cooh) to base ( naoh) and get sodium acetate ch3coohna but how do i measure solubility of sodium acetate? do i wait just until a precipitate forms at equilibrium(saturation)?
You need to let us know more about the procedure. Titration alone will not tell you the solubility. If you are using an indicator to show the end point of the titration, then molarity of NaOH*volume NaOH will be the mols CH3COONa formed and you can find the grams CH3COONa from that. But whether that dissolves or not depends upon the amount of water in the titration vessel.
