8. a) Four solutions were made up; one containing glucose, one containing starch, one containing amylase (a starch digesting enzyme) and one containing sucrose. Unfortunately, they were not labelled, except as solutions A, B, C and D. The following tests were carried out to identify the solutions. All solutions were tested with Biuret reagent cart offoege delt eqansi Solution C turns purple Solutions A, B and D remain blue Solutions A, B and D tested with Benedict's solution Solutions A and B remain blue Solution D turns red Solutions A and B incubated with Solution C and then retested with Benedict's solution Solution B turns red Solution A remains blue Identify, with reasons, the four solutions.
