Answer: The molarity of the borax solution is 0.107 M
Explanation:
The neutralization reaction is:
According to neutralization law:
where,
= basicity of
= 2
= acidity of borax = 2
= concentration of
= 1.03 M
= concentration of borax =?
= volume of
= 2.07ml
= volume of borax = 20.0 ml
Now put all the given values in the above law, we get the molarity of borax:
By solving the terms, we get :
Thus the molarity of the borax solution is 0.107 M
Dimension of the salt crystal is:
Length = 3.22 x 10^-2 cm
Breadth = 1.5 x 10^-4 cm
Height = 4.30 x 10^-3 cm
So it is cuboidal in shape.
Volume = L × B × H
Length = 3.22 x 10^-2 cm
Breadth = 1.5 x 10^-4 cm
Height = 4.30 x 10^-3 cm
So it is cuboidal in shape.
Volume = L × B × H
