balance‚ and the exact mass was recorded. The hair was then transferred to a 50cm3 conical flask‚ to which 10ml of concentrated nitric acid (69-72%) was added. The solution was then stirred and heated on a hot plate‚ for about 1 hour‚ until the hair has dissolved‚ and a dark brown solution was obtained. The solution was then left to cool‚ and then was filtered using a fluted filter paper‚ into a 50ml volumetric flask. The filtrate was then made up to the 50 ml mark‚ using deionised water.

In The Laboratory‚ the courtesan chooses poison as her murder weapon. Poison is often the weapon of choice for female killers. It requires little or no physical strength to administer‚ and can be done secretly. It also leaves little evidence thus making it difficult to detect the culprit.

Experiment: 3A The purpose of laboratory assignment 3 was to measure the rate at which a chemical reaction takes place. For the purpose of this lab we measured the rate a balanced oxidation/reduction reaction between iodine‚ hydrogen‚ and bromate ion occurs. The above reaction occurs slowly so we used a coupled iodine clock reaction to measure the rate of the oxidation/reduction reaction because it occurs much faster but is still dependent upon the other reaction. To accomplish this‚ two mixtures

The vigorous intimacy had left us quite weary and I led him into the parlor room. I placed myself upon the burgundy velvet couch and took a fresh Italian cigar from my cabinet while he sat on the chair across the dimly lighted room. He stared at me with a heavily lidded lustful gaze as he took a sip of his glass of Amontillado
