Question
When red blood cells are placed in an hypotonic solution. water flows out of the red blood cells. water flows inside the red blood cells. there is no net flow of water. the cells stay normal. Which solution will have the largest freezing point depression of water? 1.0 M CaCl_2 1.5 M NaCl 1.0 M AlCl_3 3.5 M Glucose Which compound is copper (I) chloride dihydrate? CuCl middot 2 H_2O CuSO_4 middot 2H_2O CuCl_2 middot H_2O Cucl_2 middot H_2O Decane is non-polar liquid and has density of 0.730 g/mL, water has a density of 1.00 g/ml.. 5 ml of each of decane and water is transferred to a glass test tube at room temperature. Now 5 mL of saturated iodine-water solution, which has a strong purple color, is added to the test tube. The test tube is gently shaken and then kept in a test tube rake. Which one of the following observations will hold true? The two liquids are immiscible and lower portion of liquid in the test tube will have a strong purple color. The two liquids are immiscible and upper portion of liquid in the test tube will have a strong purple color. The two liquids are miscible and liquid in the test tube will have a uniform color throughout. Decane, water and iodine will form three layers.Explanation / Answer
34) as temparature increases, dissociation of water also increases so it become acidic at higher temperature, option (c)
35)option (d) because per 100 ml solubility is 35.8g then for 150ml solubility is 53.7g
36)option(b) solutions having equal concentrations are called isotonic solutions, 0.15 *2 ions of NaCl =0.3M
0.1*3 ions of CaCl2 =0.3M
37) option (B) water flows from hypotonic (lower concentration) to blood cells (higher concentration)
38) option (c) depression in freezing point directly proportional to concentration so 1*4 ions of AlCl3
39) option (c)
40) option (d) decane and iodine are covalent molecules so that it can be soluble in organic solvents but water is inorganic solvent so three forms different layers
