Question

Ethylene glycol is mixed with water as anti-freeze in radiator. which one following is true for ethylene glycol it has low vapor pressure it raises the boiling point of water it lowers the freezing point of water it changes osmotic pressure All of the above What is the osmotic pressure of a 0.0020 mol dm^-3 sucrose (C_12 H_22 O_11) solution at 20 degree C? (Molar gas constant, R = 8.314 JK^-1 mol^-1, 1 dm^3 = 0.001 m^3? 4.870 pa 4870 pa 0.00487 pa 0.33 pa A 1,000 L solution is prepared in which Au^+, Ag^+, and Cu^+ icon are present in solution as nitrated all at a concentration of 0.0010 M. A solution of sodium chloride is slowly added. which compound will begin to precipitate first? The K_sp of AuCI = 2.0 times 10^-13; AgCI = 1.8 times 10^-10; CuCI = 1.9 times 10^-7. CuCI AgCI AuCI NaNO_3

Explanation / Answer

Ans 25) C - it lower the freezing point of water.

Ans 26) osmotic pressure = C R T

= 0.002 * 8.314 * 293

= 4.83
