she places 5 milliliters of the liquid in a test tube and adds 5 drops of Bendict solution. she transfer the test tube to a beaker of boiling water
for 5 minutes, then removes it and observes changes in the color of the solution. what other equipment does the student need to perform this experiment safely? use your knowledge of labratory safety to explain why she needs this equipment.

Benedict's test ,would tell only whether the sugar is reducing or not.--Gluocose/ Fructose/ Maltose /Lactose all will give Benedict's positive.Confirmatory test is Paper or Thin layer Chromatography.But it needs elaborate equipment arrangement.

Laboratory safety? Why don't they ask what Benedict's solution is...that sounds more useful.
Anyway...test-tube tongs?

well you definitely need goggles if youre going to be in the lab. you will need mitts, tongs and possibly gloves to remove the hot glassware. maybe a lab apron to protect from chemical splashes.
