Answer : The concentration in (M)of bromide ions in a saturated solution of mercury (II) bromide is,
Explanation :
The solubility equilibrium reaction will be:
Let the molar solubility be 's'.
The expression for solubility constant for this reaction will be,
Given:
=
Now put all the given values in the above expression, we get:
Therefore, the concentration in (M)of bromide ions in a saturated solution of mercury (II) bromide is,
Answer: The molarity of the initial concentrated solution is 0.450 M
Explanation:
According to the dilution law,
where,
= Molarity of concentrated KOH solution = ?
= volume of concentrated KOH solution = 175 ml
= concentration of diluted KOH solution= 0.315 M
= volume of diluted KOH solution= 250 ml
Putting in the values, we get:
Thus the molarity of the initial concentrated solution is 0.450 M
