solution freezing point

Colligative Properties - Depression in Freezing Point - Freezing point of a substance is defined as the temperature at which the vapor pressure of the solid form is in equilibrium with liquid form of the substance. In other words, solid and liquid forms of th..

The dilute solution of hydrogen peroxide is cooled in a freezing mixture. Water present in hydrogen peroxide solution separates out as ice. The-ice is removed. This leaves behind a solution richer in hydrogen peroxide. For most commercial purposes, concentra..

Definitions of solute and solvent The dissolving process as a result of random molecular motion Temperature, pressure, and surface area - their affect the dissolving process Concentration of a solute in terms of grams per liter, molarity, parts per million and percent co..

Freezing point of a substance is defined as the temperature at which the vapor pressure of the solid form is in equilibrium with liquid form of the substance. In other words, solid and liquid forms of the substance has same vapor pressur..

Root mean square speed, T = 27+ 273 = 300 K, M= 16. R= 8.314 x 10 7 erg k - 1 mol - 1 = 683.9 ms - ..

Liquation is a method for concentrating ores, which have a lower melting point than the impurities. The ores of antimony are concentrated by this method. The powdered ore is heated upon a sloping floor of the furnace. The temperature is raised above the melting point of the ore..

Solid water (ice) is in equilibrium with liquid water. The volume of a fixed mass of water is less than that of ice at its melting point. Therefore an increase in pressure will favour the forward reaction i.e., when pressure is applied to a system containing ice and water at equilibrium,..

Initial velocity (u) = 0 Time taken (t) = 6 seconds Acceleration due to gravity (g) = 9.8 m/s 2 We make use of second equation of motion h = 0 + 4.9 x 36 h = 176.4 m 03. A stone projected vertically upward, takes 5 seconds to reach the highest point. What is the initial velocity of ..

For an acid-base reaction, at the neutralization point, Number of equivalents of acid = Number of equivalents of base = Therefore, Acidity of the base (given) = 1 Thus, Molecular mass of the base = 1 x 45 amu = 45 ..
