The color of the dye comes from the delocalization of electrons in the πbonding system (Exton‚ 149). Bleach is an aqueous solution that contains sodium hypochlorite (NaOCl). The hypochlorite of bleach breaks the double bonds of the food dye through oxidation‚ forming molecules that do not absorb visible light and thus bleaching the product. During this process‚ hypochlorite is reduced to chloride and hydroxide ions. OCl (aq) + H2O (l) + 2e → Cl (aq) + 2OH (aq) Our goal in this experiment was to observe the reaction and concentration changes between

avoid skin and eye irritations. Adding pool chlorine (hypochlorite ion) is one way to control acidity and stop algae from growing. SOIL TESTING: Soil samples need to be tested. Many plants will only tolerate a narrow range of acid/base in the soil. For example‚ azaleas grow best in acidic soils‚ where beetroot thrives in slightly alkaline soils. One way to test this is to place a thin layer of white powder‚ such as barium sulfate or calcium sulfate‚ on the top of moist soil. Then place a few

products in a chemical equation. However‚ in the instance that the products’ mole ratios are unknown‚ it can be determined through the experiment. This method is called continuous variations. In this lab‚ I determined the mole ratio between Sodium Hypochlorite and Sodium Thiosulfate by using continuous variations of ratios in a given volume. This reaction was exothermic so I measured the heat that was produced from the reaction. Hypothesis: The reaction with the proper mole ratio will reach the highest

Tell Me About Blood 1.) What is the significance of lower-than-normal hematocrit? Lower-than-normal hematocrit indicates anemia. People with anemia do not have enough hemoglobin‚ which is the oxygen-carrying protein in red blood cells. Iron‚ B12‚ and folic acid deficiencies‚ some medications‚ and pregnancy can cause anemia. There are also more serious causes such as problems with the immune system that cause destruction of red blood cells earlier than normal‚ chronic diseases including

Experimental Part 1: Reaction First the glassware apparatus for the reaction was set up. 3.861-grams of isoborneol‚ 2.21-mL of glacial acetic acid‚ and 4.39-mL of 6% NaOCl solution were mixed in a 125-mL Erlenmeyer flask. Another 35-mL of 6% NaOCl solution was added to a separatory funnel and supported over the flask. The NaOCl in the sep funnel was slowly added into the Erlenmeyer flask with vigorous swirling‚ approximately 2-mL every 30 seconds until all the NaOCl from the sep funnel had been

INTRODUCTION Many common household chemicals are dangerous. They may be reasonably safe when used as directed‚ yet contain toxic chemicals. And one of the most dangerous household chemicals is the household bleach since it contains sodium hypochlorite‚ a chemical that can cause irritation and damage to the skin and respiratory system if inhaled or spilled on the skin and most people who get allergic reactions and minor injuries during a prolonged use. Just like lead poisoning‚ the effects
