Question

describe the final conditions. the tubing contains starch solution lugol’s solution starch solution and lugol’s solution

Explanation:

Lugol's solution is an iodine - potassium iodide solution. It reacts with starch to form a blue - black complex. If the tubing contains starch solution and Lugol's solution diffuses into it, a color change will occur. If only starch solution is in the tubing, there is no reaction yet until Lugol's solution diffuses in. If only Lugol's solution is in the tubing, there is no starch to react with.

Answer:

starch solution and Lugol's solution
