means that cells which are not viable would not take up the dye and due to their age and not their ability to break down the methylene blue (as a result of their viability) would remain colourless and be determined to be viable (a false positive). The test itself is also not very accurate since yeast might not be evenly distributed in the original sample and depending on the

Forming Methyl Orange an Azo Die Abstract: An synthetic azo dye was created by reaction of diazonium salt with N‚N-Dimethylanaline. The final product created was 4-dimethylaminoazobenzene-4-sulfonic acid‚ an orange clay-like substance. Sulfanilic acid was chemically manipulated by using sodium carbonate followed by cooled sodium nitrate and hydrochloric acid to form the diazonium salt used in the reaction. The products were washed in ethanol. The product was obtained at an 84% yield and was

Synthesis of Benzanilide and Methyl 3-Nitrobenzoate and the Identification of ‘Unknowns’ from Spectroscopic and Physical Properties James Lucas 10394308 23/11/12 Introduction In this series of practicals it was the aim to synthesise both Benzanilide and Methyl 3-Nitrobenzoate. Benzanilide was synthesised using The Schotten Baumann reaction which takes a hydrogen atom from an amino group and substitutes it for an acyl group. For Methyl 3-Nitrobenzoate‚ NO2+ was used as an

A red–black tree is similar in structure to a B-tree of order[note 1] 4‚ where each node can contain between 1 to 3 values and (accordingly) between 2 to 4 child pointers. In such B-tree‚ each node will contain only one value matching the value in a black node of the red–black tree‚ with an optional value before and/or after it in the same node‚ both matching an equivalent red node of the red–black tree. One way to see this equivalence is to "move up" the red nodes in a graphical representation
