Well, assuming an aqueous solution of this exists, then the theoretical
Explanation:
We first need to calculate the molarity of this solution.
Sodium acetate has a chemical formula of
Molarity is expressed by the formula
We therefore need to convert the sodium acetate into moles, and the volume into liters.
Then,
Since sodium acetate is a salt formed by neutralization of acetic acid and sodium hydroxide (see the equation):
where
Acetic acid is a weak acid, while sodium hydroxide is a strong base, so an aqueous sodium acetate solution would be slightly basic.
Therefore, we would need to calculate the
So, the
We know that at
So, the solution would have a
Well, we solve the equilibrium expression....but we need more data.
Explanation:
And as always for equilibria...
Of course, you have not quoted
And so
And if we say that
We could solve for
And so
But
