Solubility of a gas in a liquid is directly proportional to the partial pressure of that gas above the liquid. Solubility of a gas is inversely proportional to temperature.
So, the solubility of carbon dioxide gas in water is increased by increasing the partial pressure of carbon dioxide and by decreasing the temperature.
Quartz is the type of mineral used for both mechanical and chemical weathering
⇒ a reddish, brownish color
⇒ has a shine/glow
⇒ excellent conductor
Solvation is the process of dissolving.
Dissociation is the separation of a substance into charged components during dissolution.
<h3>What is the difference between dissolving and dissociating?</h3>
Dissolution (dissolving), which simply refers to becoming solvated by the solvent, is a subset of dissociation, which is particularly the separation of two charged ions in solution. When the solvent completely envelops each individual solute molecule, solvation takes place. By definition, something that is dissociated in a solvent must be dissolved in it. For instance, the salt dissociates in water, which is how it dissolves in water. In water, ethanol dissolves but does not dissociate; it remains ethanol.
<h3>How does Van't Hoff's factor work?</h3>
The Van't Hoff factor is a tool used to compare the real number of moles of solute injected to create a solution to the apparent amount produced by colloidal characteristics.
<h3>What is the Van't Hoff factor's value?</h3>
Van't Hoff factor's value is:-
- No association or dissociation i=1
- Dissociation i<1
- Association i>1

Aluminum hydroxide 
can behave as a base and neutralize sulfuric acid 
as in the following equation:
(Balanced)
(a)
. Thus the ratio between the number of moles of the two reactants available:
![n(\text{Al}(\text{OH})_3, \text{supplied}) / n(\text{H}_2\text{SO}_4, \text{supplied})\\= [m(\text{Al}(\text{OH})_3)/ M(\text{Al}(\text{OH})_3)] / [n(\text{H}_2\text{SO}_4) / M(\text{H}_2\text{SO}_4)]\\= [23.7 / (26.98 + 3 \times(16.00 + 1.008))]/[29.5 / (2 \times 1.008 + 32.07 + 4 \times 16.00)]\\\approx 1.01](https://tex.z-dn.net/?f=n%28%5Ctext%7BAl%7D%28%5Ctext%7BOH%7D%29_3%2C%20%5Ctext%7Bsupplied%7D%29%20%2F%20n%28%5Ctext%7BH%7D_2%5Ctext%7BSO%7D_4%2C%20%5Ctext%7Bsupplied%7D%29%5C%5C%3D%20%5Bm%28%5Ctext%7BAl%7D%28%5Ctext%7BOH%7D%29_3%29%2F%20M%28%5Ctext%7BAl%7D%28%5Ctext%7BOH%7D%29_3%29%5D%20%2F%20%5Bn%28%5Ctext%7BH%7D_2%5Ctext%7BSO%7D_4%29%20%2F%20M%28%5Ctext%7BH%7D_2%5Ctext%7BSO%7D_4%29%5D%5C%5C%3D%20%5B23.7%20%2F%20%2826.98%20%2B%203%20%5Ctimes%2816.00%20%2B%201.008%29%29%5D%2F%5B29.5%20%2F%20%282%20%5Ctimes%201.008%20%2B%2032.07%20%2B%204%20%5Ctimes%2016.00%29%5D%5C%5C%5Capprox%201.01)
The value of this ratio required to lead to a complete reaction is derived from coefficients found in the balanced equation:
The ratio for the complete reaction is smaller than that of the reactants available, indicating that the species represented on the numerator, , is in excess while the one on the denominator, , serves as the limiting reagent.
(b)
The quantity of water produced is dependent on the amount of limiting reactants available. 
of sulfuric acid is supplied in this reaction as the limiting reagent. 
moles of water molecules are produced for every 
moles of sulfuric acid consumed. The reaction would thus give rise to 
of water molecules, which have a mass of 
.
(c)
(d)
The quantity of , the reactant in excess, is dependent on the number of moles of this species consumed in the reaction and thus the quantity of the limiting reagent available. The consumption of every moles of sulfuric acid, the limiting reagent, removes 
moles of aluminum hydroxide from the solution. 
of sulfuric acid is initially available as previously stated such that 
, or 
, of would be eventually consumed.
of would thus be in excess by the end of the reaction process.
