Which of the following combinations cannot produce a buffer solution?, HNO2 and NaNO2, HCN and NaCN, HClO4 and NaClO4, NH3 and (NH4)2SO4, Colligative properties of dilute solutions of nonelectrolytes depend on …, on the nature of the dissolved substance, on the temperature, on the number of particles in the solution, on the pressure, A spontaneous process of solvent transfer through a semipermeable membrane from a less concentrated solution to a more concentrated one, dialysis, osmosis, ultrafiltration, diffusion, When two solutions with different osmotic pressures are in contact through a semipermeable membrane, the solution whose osmotic pressure is higher is called …, hypertonic, isotonic, hypotonic, aqueous, The isotonic coefficient i in real aqueous solutions of electrolytes takes values …, i < 1;, i > 1., i = 1;, i >>1;, The cell loses water and undergoes plasmolysis (shrinking)., swelling of the cell with the development of turgor pressure, no answer, rupture of the cell, shrinking of the cell membrane – plasmolysis, Saturated vapor over a solution of a non-volatile nonelectrolyte is formed by:, water molecules, nonelectrolyte molecules, water and nonelectrolyte molecules, no answer, Only nonelectrolytes are listed in:, sodium chloride, hydrochloric acid, sodium bicarbonate , glucose, sodium chloride, acetic acid, benzene, glucose, sulfur, hydrogen sulfide, carbonic acid, sodium carbonate, The boiling point of a solution relative to the boiling point of the pure solvent:, decreases, no answer, does not change, increases, The degree of dissociation of a weak electrolyte upon dilution of the solution:, decreases inversely proportional to the square root of its molar concentration, increases directly proportional to the square root of its molar concentration, increases inversely proportional to the square root of its molar concentration, does not change.
