Answer:
ΔG = -8.812 kJ/mol
Explanation:
To obtain the free energy of a reaction you can use the expression:
ΔG = ΔG° + RT ln Q
<em>Where: </em>
<em>ΔG° is Standard Gibbs Free energy: -16.7kJ/mol = -16700J/mol</em>
<em>R is gas constant: 8.314472 J/molK</em>
<em>T is absolute temperature (37°C + 273.15 = 310.15K)</em>
<em>And Q is reaction quotient: 21.3</em>
<em />
Replacing in the formula:
ΔG = ΔG° + RT ln Q
ΔG = -16700J/mol + 8.314472J/molK*310.15K ln 21.3
ΔG = -8812.4J/mol
<h3>ΔG = -8.812 kJ/mol</h3>

To dissolve in water, aluminum (Al) should form a compound with sulfate. Aluminum sulfate is the water soluble compound of aluminum. It has a chemical formula of Al2(SO4)3. It is used in industries as flocculating agent especially in the purification steps of drinking water and wastewater treatment plants.
In ionic bonding, an arrow is often drawn on the diagram to show the direction the electrons move to form the ions.
