Which one is limp and which one is crisp?Answer The potato strip in first test tube appears crispy, while in other appears limp.That is the potato strip present in sugar solution is crispy, while in salt solution is limp.B.How can the difference be explained?Answer The difference is due to concentration of solution,C.What caused the change in appearance of each strip?Answer If solution is less concentrated (sugar solution) than potato, its waterenters in it andprovides potato’s strip a crisp appearance, but if it is more concentrated than potato,then,water from potato comes outside and potato’s strip limps.
