ABSTRACT ABSTRACT The researchers conducted a study about Kamias (Averrhoa bilimbi) and Dalandan (Citrus aurantium) as alternative decolorizers in Gram Staining bacteria. Kamias (Averrhoa bilimbi) has a high oxalic acid content‚ fruit used to remove stains from clothing and for washing hands‚ removing rust and stains from metal blades. Dalandan (Citrus aurantium) is an aromatic variety

LITERATURE The bilimbi‚ Averrhoa bilimbi‚ L.‚ (Oxalidaceae)‚ is closely alliedto the carambola but quite different in appearance‚ manner of fruiting‚flavor and uses. The only strictly English names are "cucumber tree"and "tree sorrel"‚ bestowed by the British in colonial times. "Bilimbi" isthe common name in India and has become widely used.Bilimbisare all much the same wherever they are grown‚ but P.J.Wester reported that a form with sweet fruits had been discovered inthe Philippines. The bilimbi is a tropical

Bleach – And How It Works! Yes‚ knowing how bleach works isn’t all that exciting‚ but since bleach is what you usually use in your daily life‚ why not understand how and why it works? Wonder how the colour of the liquid is a yellowish colour‚ but the clothes come out as pure white? Or maybe why your parents always tell you not to touch bleach because it harms your skin? Since we’re still young‚ why not understand it earlier? Bleach has two forms: chlorine bleach and non-chlorine bleach.

Solar bottled light bulb is easy to assemble and the procedure use‚ in an empty clear container of soda‚ add at least 1.5 liter mineral water and 2tblespoon of liquid bleach‚ with that it will be covered half of roof sheet and exposed to sunlight. The bottle is inserted halfway through a hole drilled in the metal roof and its sides are sealed. The whole deal looks like a bulb through a sunroof and provides a good amount

To determine the rate law with respect to bleach and blue dye‚ a series of graphic and algebraic manipulations were done on the data obtained in the kinetic trace experiment in order to determine the different components that made up the rate law. Using absorbance spectroscopy to monitor concentration over time‚ rate order of the dye was found to be 1st order through the integrated rate law and through the proportionality method; the order of the bleach was also determined to be 1st order.

purpose of this lab was to determine the effectiveness of antiseptics‚ disinfectants‚ and antibiotics on bacteria. The hypothesis was that if bleach was used‚ it would be the most effective because bleach is commonly used to clean and disinfect various things. The variables that were tested were antibacterial soap and Scope mouthwash for the antiseptics; bleach and ammonia for the disinfectant; and Cipro‚ erythromycin‚ and tetracycline for the antibiotics. All of these chemicals were used on the bacteria

were studied. Elodea was inserted into different beakers. One containing water and the other‚ bleach. The elodea was left unattended for an hour so that observations could be made to tell the difference in the results each beaker produced. After an hour the quantity of CO2 present was measured for the beaker with water and the beaker containing bleach. The results recorded were inconclusive because the bleach had a buffer that evidently lowered the pH‚ the beaker that had water in it showed signs that

will demonstrate how a chemical reaction from vinegar‚ water‚ and bleach can accelerate the rusting process of steel. If steel wool pads are submerged in bleach‚ water‚ and vinegar‚ then the steel wool pads will rust faster in water because Electrolytes accelerate the corrosion process when combined with water. Materials and Procedure: you will need: Steel wool pads (the soap-free kind) 3 Medium sized jars Water Vinegar Bleach Procedure: 1. Place the steel wool pad into the jar. 2. Fill
