'Observations of Chemical Changes Essay\r'

'Objective: This experiment is meant to give how certain chemical substances react with each new(prenominal) and can be identified by these reactions Procedure: Several different chemical mixs were pou wild into the well plate and observed. These included atomic number 11 bicarbonate and hydrochloric stingingulated, bromothymol blueness and hydrochloric acid, ammonia and bromothymol blue, hydrochloric acid and blue dye, blue dye and sodium hypochlorite, potassium iodide and lead nitrate, sodium hydroxide and phenolphthalein, hydrochloric acid and phenolphthalein, sodium hydroxide and carve up nitrate, ammonia and silver nitrate, and ammonia and hair (II) sulfate. Some mixtures were also placed in the light or mixed with extra hydrochloric acid or dye.\r\nObservation duck:\r\nQuestions: a.) Silver nitrate could easily be used to test for sodium bicarbonate since it becomes the chemical to turn brown. b.) Windex- turns orange with BTB and cherry-red with phenolphthalein- motif Dish soap- turns color with BTB and red with phenolphthalein- base Bleach- turns orange with BTB and purple with phenolphthalein- base Scrubbing Bubbles- turns blue with BTB and gray with phenolphthalein- acid c.) The solution contains no vinegar or a very small add together of vinegar because a pink cloak indicates a basic solution, and vinegar is and acid. d.) The yellow flavor is more acidic and the blue flavor is more basic. e.) Combining the mixture with potassium iodide could easily test for the forepart of lead. If the mixture contained lead, then the potassium iodide would cause the mixture to turn yellow and boneheaded like a solid.\r\nConclusion: many chemicals will produce obvious physical changes when mixed with other chemicals. These mixtures usually import in a change in color or consistency, which can key out them from other chemicals. While certain chemicals may react the same way with on mixture, testing a chemical with fivefold mixtures will most l ikely brook the chemical to be identified.\r\n'
