A reaction between acid and base to form water and salt is known as neutralization reaction. It is a double replacement reaction.
The reaction between and
will be:
The balanced reaction is:
Volume of = 28 mL (given)
Since, 1 L = 1000 mL
So, 28 mL = 0.028 L
Molarity of = 5.4 M (given)
Molarity = -(1)
Substituting the values in equation (1):
From the balanced reaction between and
, 2 moles of
reacts with 1 mole of
.
Molar mass of = 84.007 g/mol
Mass of needed:
=
Hence, the required amount of is
.
