Explanation:
Answer : The pH of 0.289 M solution of lithium acetate at is 9.1
Explanation :
First we have to calculate the value of .
As we know that,
where,
= dissociation constant of an acid =
= dissociation constant of a base = ?
= dissociation constant of water =
Now put all the given values in the above expression, we get the dissociation constant of a base.
Now we have to calculate the concentration of hydroxide ion.
Formula used :
where,
C is the concentration of solution.
Now put all the given values in this formula, we get:
Now we have to calculate the pOH.
Now we have to calculate the pH.
Therefore, the pH of 0.289 M solution of lithium acetate at is 9.1
