What chemical species are produced when borax dissolves in water?
1 answer:
It hydrolysed to form sodium borate, NaB(OH)4 and boric acid.
<u>Explanation</u>
Borax is an important mineral, boron compound and is a salt of 'boric acid'. The powdered borax consists of soft colourless crystals that will dissolve in water. It is used in many detergents, enamel glazes and cosmetics.
When mixed with water it produces to form an ion known as the borate ion. Thus hydrolysed to form sodium borate, and boric acid that is chemically written as B(OH)3 or

Explanation:
The given data is as follows.
T = = (120 + 273.15)K = 393.15 K,
As it is given that it is an equimolar mixture of n-pentane and isopentane.
So, = 0.5 and
= 0.5
According to the Antoine data, vapor pressure of two components at 393.15 K is as follows.
(393.15 K) = 9.2 bar
(393.15 K) = 10.5 bar
Hence, we will calculate the partial pressure of each component as follows.
=
= 4.6 bar
and,
=
= 5.25 bar
Therefore, the bubble pressure will be as follows.
P =
= 4.6 bar + 5.25 bar
= 9.85 bar
Now, we will calculate the vapor composition as follows.
=
= 0.467
and,
=
= 0.527
Calculate the dew point as follows.
= 0.5,
= 0.5
= 0.101966
P = 9.807
Composition of the liquid phase is and its formula is as follows.
=
= 0.5329
=
= 0.467
