    Henry's law:
    The law states that at a constant temperature, the solubility of a gas in a liquid is directly proportional to the pressure of the gas.
    The most commonly used version of Henry's law is: "The partial pressure of a gas in vapour phase (p) is proportional to the mole fraction of the gas (χ) in a solution."
    p ∝ χ
    p =KH χ
    Where KH = Henry's law constant.

    Amount of gas which is dissolved in liquid solution directly proportional to the partial pressure of that gas which is above liquid surface. Or you can say that the solubility of a gas in liquid solution is directly proportional to the partial pressure of that gas above liquid surface.

    There are three types of solution. 1) solid solution it is defined as solution of solid solution.2) liquid solution defined as solution of liquid is called liquid solution and third is gas solution defined as the solution of gas particles solution in this 3 solution the solvent which is used in 3 solution is solid liquid and gas it is another matter What You Mix in this solution which is called solute

    Normality is defined as the number of equivalent mass dissolved in per unit litre of solution is called normality. Normality is equal to molecular weight by x where X is denoted by valency factor of anion cation and salt electrolyte and divided by per litre solution

    when a non-volatile solid is added to the solvent its vapour pressure decreases and now it would become equal to that of solid solvent at lower temperature. Thus, the freezing point of the solvent decreases

    1 litre water = 1 kg i.e. 1000 g water (∵ d = 100 kg/m3)
    ≡ 1000/18 = 55.55 moles of water
    So, molarity of water = 55.55M

    When impure titanium or zicronium reacts with Iodine to form TiI4 or ZrI4 which later decomposes to give pure titanium or zicronium because iodine being more covalent volatiles off eg.Zr+2I2 gives ZrI4 which later decomposes at 2075k to give pure zicronium

    Van Arkel method (Vapour Phase Refining )
    This method is based on the thermal decomposition of metal components. The process of decompositon of a compound into different substances due to the supply of heat is called thermal decomposition.

    Titanium metal is purified by this method. When the impure titanium metal is heated with iodine at a temperature of 2500 C, volatile titanium tetra-iodide is formed (TiI4). The impurities are left behind, as they do not react with iodine.
    The titanium tetra-iodide vapour is passed over a hot tungsten filament at 14000 C. The vapour is decomposed and pure titanium is deposited on the filament and is removed. The iodine is reused.
