what would give a positive result with the benedicts test
Benedict's reagent It is a complex mixture of sodium carbonate, sodium citrate and copper(II) sulfate pentahydrate, [2], which is often used in place of Fehling's solution to detect the presence of reducing sugars. The presence of other reducing substances also gives a positive reaction.[3] Such tests that use this reagent are called the Benedict's tests. A positive test with Benedict's reagent is shown by a colour change from clear blue to a brick-red precipitate.
SAT Subject Test in Chemistry The test has 85 multiple choice questions, each consisting of five answer choices, that are to be answered in one hour. Students receive 1 point for every correct answer, lose Â¼ of a point for each incorrect answer, and receive 0 points for questions left blank. This score is then converted to a scaled score of 200-800. The mean score for the 2009 test administrations was 638, standard deviation 113.[1] In 2011, the mean score was 648 with a standard deviation of 110.
