A hydrate of chromium(II) sulfate (CrSO4·XH2O) decomposes to produce 19.6% water & 80.4% AC. Calculate the water of crystallization for this hydrated compound. (The molar mass of anhydrous CrSO4 is 148.1 g/mol.)
In other words, what is the X in the formula: CrSO4·XH2O?
Decaffeinated coffee is produced by extracting the caffeine from coffee with a solvent. Initially dichloromethane (CH 2Cl 2) was used, but concerns arose over the ill health effects of trace amounts of CH 2Cl 2 remaining in the coffee. Why is caffeine soluble in CH 2Cl 2?
Octane (C8H18) boils at 125°C as compared to water which boils at 100°C. This information suggests that the IMFA in nonpolar octane molecules are stronger than those in water.

- Suppose you are presented with a clear solution of sodium thiosulfate, Na2S2O3. How could you determine whether the solution is unsaturated, saturated, or supersaturated?arrow_forwardConsider this information regarding two compounds. Thallium azide: yellow crystalline solid; melting point = 330 C; slightly soluble in water, more soluble in hot water; insoluble in ethanol or diethyl ether. Camphene: colorless, cubic crystals; melting point = 51 C; boiling point = 159 C; insoluble in water; moderately soluble in ethanol; soluble in diethyl ether. (a) Is camphene an ionic or molecular compound? Explain your answer. (b) Is thallium azide an ionic or molecular compound? Explain your answer.arrow_forwardThe solubility of acetanilide in hot water (5.5 g/100 ml at 100 o C) is not very great, and its solubility in cold water (0.53 g/ 100 ml at 0 o C) is significant. What would be the maximum theoretical percent recovery from the crystallization of 5.0 g of acetanilide from 100 ml water. (assuming the solution is chilled at 0 o C).arrow_forward

However, this solvent is not a good choice. Explain.arrow_forwardexplain why there is a differnce in the conductivity of tap water compared to distilled waterxarrow_forward
- State a reason of the following statement: (i) Soap do not work in hard water. (ii) The use of the sweetener aspartame is limited to cold foods and drinks.arrow_forwardEthylene glycol, CH2OHCH2OH is a liquid at room temperature and dissolves into water in all proportions. However, butane, C4H10, is a gas at room temperature and is insoluble in water. How do you account for these differences?arrow_forwardA small storage cabinet 2m x 2m x 3m contains an open 208 L drum of aqueous TEC at a concentration of 120 mg/L. The cabinet has been closed for over 2 months, so equilibrium conditions have been established. What is the TCE concentration in the water and vapor phases at this time? Assume that the temperature is 25 oC, R = 8.2 x 10-5 m3•atm/mole/K, and H = 0.0091 m3•atm/molearrow_forward
- 1. Steam distillation was performed to obtain geraniol (MM = 154.25 g/mol) from dried rose petals. At 99.25°C, the vapor pressure of water is 714 mmHg while that of geraniol was determined to be 46 mmHg. a. Determine the theoretical mass of geraniol that will distill per 100 g of water. b. If 150 g of dried rose petals were used, calculate the percent yield of the distillation.arrow_forwardYou synthesized a sample of tetramethylammonium triiodide and managed to measure the melting point. However, the melting point deviates from the ideal melting point for tetramethyl-ammonium tri-iodide, which is 117 degrees C. This suggests that your sample may be impure. Unfortunately, you ran out of time and were unable to carry out the gravimetry. Your demonstrators agreed to help you out, but instead of using gravimetry, they carried out the elemental analysis of your product. The sample contains C - 9.27 %, H -2.33 %, and N - 2.70 %. How many iodine atoms does your sample have according to this analysis?arrow_forward2. a) How could you calculate a water pressure above a 1M NaCl solution (salt in water)? Could you explain what the meaning of your formula? What would be the boiling temperature of such solution at a normal external pressure? b) How could you separate components by distillation? Explain on a phase diagram.arrow_forward
