Forty years ago‚ when women at Minamata Bay‚ Japan‚ ate fish contaminated with methyl -mercury from pollutants‚ their children were exposed to high levels in utero and were born with developmental and neurologic disorders. Methyl -mercury poisoning also occurred in Iraq following consumption of seed grain that had been treated with a fungicide containing

A. For acids * Place 2ml each of dilute acetic acid‚ hydrochloric acid‚ sulfuric acid‚ carbonated drink (colorless) and calamansi juice extract in separate test tubes. Test every solutions with blue and red litmus paper. Then add a drop of methyl orange indicator to each solutions. Record the data then wash and clean the test tube * Place another 2ml of the same acids in separate test tube. Test with a drop of phenolphthalein indicator. Then repeat the test with one drop of

derivative methyl formate results‚ according to the chemical equation:[4] CH3OH + CO → HCO2CH3 In industry‚ this reaction is performed in the liquid phase at elevated pressure. Typical reaction conditions are 80 °C and 40 atm. The most widely-used base is sodium methoxide. Hydrolysis of the methyl formate produces formic acid: HCO2CH3 + H2O → HCO2H + CH3OH Efficient hydrolysis of methyl formate requires a large excess of water. Some routes proceed indirectly by first treating the methyl formate

Title Biochemical Analysis of Blood Abstract Introduction After blood is collected from a patient it is analysed to check the fragments present and the fluid which will either be plasma or serum. After plasma is separated from blood it recollects the fibrinogen which in turn helps in clotting however serum is the portion of blood which remains after the fibrinogen is removed. Serum contains approximately 6-8% of the proteins which make up blood however plasma creates up to 55% of blood

indicator is added to the solution‚ they bind to hydrogen or hydroxide ions. The different electron configurations of the bound indicator cause the indicator ’s colour to change. Some common indicators are: universal indicator‚ phenolphthalein‚ methyl orange‚ litmus‚ bromothymol blue. However‚ there are some indicators that are found in nature in the form of plant pigments known as anthocyanins‚ which change colour over different pH ranges‚ depending on source. For example red cabbage juice will

The product was supposed to turn a dark gray but ended up being browner likely due to the addition of too many iodine crystals by accident. The reagent was then reacted with a solution of diethyl carbonate and tetrahydrofuran to produce the dye methyl violet (Figure 1). This caused the solution to turn a dark blue until hydrochloric acid was added to turn the solution to violet. When hydrochloric acid was added a solid precipitate formed. The resulting dye was absorbent to the fabrics bleached
