1.	Why zinc was applied in the corners of the test tubeplease explain
Answer» Answer: Zinc reacts with sulfuric acid to produce hydrogen. The REACTION is catalysed by copper. In this practical, STUDENTS can compare the rate of reaction (with and without copper) by means of the rate of PRODUCTION of hydrogen gas bubbles. This is a quick and easy experiment that can be DONE individually or in pairs. I hope it's help you
