An aqueous solution of 2.7mmol of magnesium hydroxide, Mg(OH)2, is titrated with acetic acid. How many equivalents of acetic acid were used for titration?
How many moles of acetic acid were used?
Homework Answers
The balanced chemical equation between Mg(OH)2 and acetic acid is shown below,
It is clear from the balanced chemical equation, that 1 equivalent of Mg(OH)2 requires 2 equivalents of acetic acid. Therefore, 2 equivalents of acetic acid is used for titration.
From the balanced chemical equation, 1 mole of Mg(OH)2 requires 2 moles of acetic acid. Therefore we can consider,
number of mmoles of acetic acid = 2 x Number of moles of Mg(OH)2
= 2 x 2.7 = 5.4 mmol of acetic acid
Therefore, 5.4 mmoles of acetic acid will be used.
