Henry's law dictates that when temperature is constant, the solubility of the gas corresponds to it's partial pressure. Consider the following formula of Henry's law: p = kh c (3) (3) p = k h c. where: p p is the partial pressure of the gas above the liquid, kh k h is Henry's law constant, and. c c is the concentrate of the gas in the liquid.

Solubility
Example of a dissolved solid (left) Formation of crystals in a 4.2 M ammonium sulfate solution. The solution was initially prepared at 20 °C and then stored for 2 days at 4 °C. In chemistry, solubility is the ability of a substance, the solute, to form a solution with another substance, the solvent. Insolubility is the opposite property, the inability of the solute to form such a solution.
2.2: Solubility Lab
In each measurement you mix known masses of the salt and the water. Problem 1: Figure 2.2.2 2.2. 2 (a) is reading the temperature of a saturated solution, the problem is we do not know the concentration of the salt that dissolved. That is, the total salt added is the mass of the salt dissolved and the mass of the precipitate.
14 Effect of Temperature and Solvent on Solubility
For many solid solutes in liquid solvents (as we see from everyday life) the solubility of the solute increases with temperature. However, this is not a hard and fast rule. For example, if you look at the solubility curve of cadmium selenate above, the solubility decreases as a function of temperature.
Principles of Solubility

9.4: The Effect of Temperature on Solubility
According to the solubility curve in Figure 9.4.1 9.4. 1, approximately 48g 48 g of KNO3 KNO 3 will dissolve at 30°C 30 ° C. This means that the solution will be saturated since 48g 48 g is less than 80g 80 g. We can also determine that there will be 80 − 48 = 32 g 80 − 48 = 32 g of undissolved KNO3 KNO 3 remaining at the bottom of the ...
The 11 Solubility Rules and How to Use Them
Salts containing Cl -, Br -, or I - are generally soluble. Important exceptions to this rule are halide salts of Ag+, Pb2+, and (Hg2)2+. Thus, AgCl, PbBr2, and Hg2Cl2 are insoluble. Most silver salts are insoluble. AgNO3 and Ag (C2H3O2) are common soluble salts of silver; virtually all others are insoluble.
Solubility
The concentration of salt in the solution at this point is known as its solubility. The solubility of a solute in a particular solvent is the maximum concentration that may be achieved under given conditions when the dissolution process is at equilibrium. Referring to the example of salt in water: NaCl(s)⇌Na+(aq)+Cl−(aq).
PDF Lab 2: Developing and Testing a Hypothesis
A hypothesis is an educated guess regarding the outcome of an experiment. A good hypothesis is one that is testable and that can be modified and improved based on the outcome of experimental results. In organic chemistry lab, you will often be expected to develop a hypothesis, and test that hypothesis during your experiment.

How Temperature Influences Solubility
How Temperature Influences Solubility. The solubility of a substance is the amount of that substance that is required to form a saturated solution in a given amount of solvent at a specified temperature. Solubility is often measured as the grams of solute per 100 g of solvent. The solubility of sodium chloride in water is 36.0 g per 100 g water at 20°C.

Science Experiments on Solubility
A common hypothesis states that hot water will dissolve more solute than cold water. Use this experiment to determine if temperature has any effect on solubility. Add a 1/2 cup of lukewarm tap water to a plastic cup. Weigh about 5 tablespoons of salt and gradually add the salt to the tap water, stirring to mix.

Perspectives in solubility measurement and interpretation
The solubility of haloperidol exceeded 300 mg/g aqueous solution of malic acid. This was an extremely high aqueous solubility for haloperidol, considering that its intrinsic aqueous solubility in water as the free base is only 0.7 μg/mL, and the solubility of its salt forms (e.g., HCl, phosphate, maleate) is only about 1-5 mg/mL.
