Cutting equal-sized potato pieces and measuring initial weight ensures fair comparison. It helps observe accurate changes due to osmosis, avoiding errors caused by size or mass differences in the experiment results.
Why is it important to cut the two potato pieces in roughly equal size and measure their initial weight before placing them in different liquids?

Using potato pieces of equal size and measuring their initial weight ensures that any observed change is due to the solution and not differences in size or mass. This makes the experiment reliable and accurate. It helps compare results properly and clearly shows the effect of osmosis on the potato pieces placed in different solutions.
