The graph showing an increase in solubility of potassium nitrate with increasing temperature best describes its solubility in water. This is because potassium nitrate has a positive solubility-temperature relationship, meaning its solubility increases as the temperature of the water increases.
In general, solubility decreases as temperature increases for gases due to the decrease in gas solubility with higher temperatures. Helium shows minimal change in solubility with temperature because it is very nonpolar and does not interact strongly with water molecules, making its solubility relatively insensitive to temperature changes.
One way to increase the solubility of a gas is to decrease the temperature of the liquid. The solubility of a gas in a liquid is usually temperature dependent, although it depends on the particular combination of which gas and which liquid. Usually the solubility of a gas goes down with increasing temperature (think of warm carbonated beverages going flat).The other way to increase the solubility is to increase the pressure of the gas. The higher the pressure of the gas above the liquid, the more will dissolve. Again, think of a carbonated beverage: when it is sealed it doesn't go flat because it is under pressure, but when open to air, it will go flat.See the Web Links to the left of this answer for more
Sodium sulfate is highly soluble in water, but insoluble in most organic solvents. If you want to increase its solubility in water (as for any salt), you can heat the solution or remove one of the products (sodium ions or sulfate ions) from solution. I can't think of any insoluble sodium salts, but barium sulfate (BaSO4) is insoluble in water. Thus, adding barium chloride (or some other soluble barium salt) will remove sulfate from the equilibrium (due to BaSO4 precipitation) and increase the solubility of sodium sulfate.
Salinity is increased by changes in salt/solute concentration. This can be caused by increases in water temperature which leads to greater solubility of salt in water or increased evaporation.
The solubility of sodium chloride in water at 20 0C is approx. 360 g/L.
1) Strong solute-solvent greater solubility while weak solute-solvent attractions equate to lesser solubility 2) Temperature (for gaz high temperature decrease solubility) 3) Pressure for solubility gaz in liquid 4) Polarity of solvent: Like dissolves like
The solubility of gases in liquids increase when pressure increase.
Knowing the solubility of an unknown substance in water can help you calculate its molarity. It is however important to get its weight first.
The reason that it effects the solubulity of oxygen is that it is gaseous while NaCl is solid at room temperature. The oxygen molecules are effected by the increase in pressure in the way that there are more of them per unit volume of air if you increase air pressure. This is clearly not the case for the Na and Cl atoms which are ionically bonded to one another and are therefore solid. If you want to know more about the reason that pressure effects the solubility of oxygen in water, have a wee look at partial pressures.
