Boiling and freezing points are colligative properties, meaning The osmotic pressure of the blood forces waste molecules and excess water through the membrane into the sterile solution. A 0.500 L sample of an aqueous solution containing 10.0 g of hemoglobin has an osmotic pressure of 5.9 torr at 22 C. Recall that the normal boiling point of a substance is the temperature at which the vapor pressure equals 1 atm. The main function of the kidneys is to filter the blood to remove wastes and extra water, which are then expelled from the body as urine. 0000012895 00000 n 3) Al3+ is highly charged species in nature and it can polarize the electron clouds of Cl to a large extent. We store cookies data for a seamless user experience. CaCl2 will dissociate into three particles in solution. Here is one set of steps that can be used to solve the problem: What is the molar mass of a protein if a solution of 0.02 g of the protein in 25.0 mL of solution has an osmotic pressure of 0.56 torr at 25 C? The use of perfusionists has grown rapidly since the advent of open-heart surgery in 1953. This phenomenon is called boiling point elevation. In one form of dialysis, called hemodialysis, a patients blood is passed though a length of tubing that travels through an artificial kidney machine (also called a dialysis machine). Osmotic pressure explains why you should not drink seawater if you are abandoned in a life raft in the middle of the ocean. The chlorine atom has a covalent radius of 1024 pm and its Van der Waals radius is 175 pm. Because the solubilities of both salts decrease with decreasing temperature, the freezing point can be depressed by only a certain amount, regardless of how much salt is spread on an icy road. To learn more, see our tips on writing great answers. Where is the magnetic force the greatest on a magnet. Freezing point depression occurs when a solute is added to a solvent producing a solution having lower freezing point temperature than the pure solvent. Here, we will focus on liquid solutions that have a solid solute, but many of the effects we will discuss in this section are applicable to all solutions. 0000044216 00000 n Asked for: concentrations
