When a potato is placed in a concentrated sugar solution, water will move out of the potato cells via osmosis, resulting in the potato shrinking and becoming soft and limp. This is because the sugar solution has a higher solute concentration than the potato cells, causing water to move from an area of higher water concentration (inside the potato) to an area of lower water concentration (the sugar solution).
Water moves from an area of higher water concentration (dilute solution) to an area of lower water concentration (concentrated solution) in osmosis. This movement occurs across a semi-permeable membrane.
When you place concentrated sugar syrup in the refrigerator, the lower temperature slows down the movement of molecules. The molecules within the syrup become more closely packed together, causing the sugar molecules to settle at the bottom due to their high density. This process is known as sedimentation.
To prepare a stock solution of Leishman stain, mix the Leishman stain powder with a suitable solvent like methanol or ethanol to make a concentrated solution. Filter the solution to remove any undissolved particles. Store the solution in a dark and cool place, away from light and heat.
The potato contains moisture that can act as a electrolytic solution. The electric voltage is created by placing to different metals, usually zinc and copper, into the potato. The potato only acts as a place for the reaction to take place. By itself, a potato has no electric value. If zinc is used the reaction follows: Zn → Zn2+ + 2 e-. Note the 2 free electrons produced, this causes the electric potential to develop between the poles of the potato battery. The total voltage produced depends on the metals used but usually peaks under 1v (~0.8v really).
When HCl is added to sodium thiosulfate, a redox reaction takes place, resulting in the formation of solid sulfur (S) and sodium chloride (NaCl) in solution. Additionally, the reaction produces sulfur dioxide gas (SO2) and water (H2O) as byproducts.
When a potato is placed in a salt solution, osmosis occurs. Water molecules move from an area of higher concentration (inside the potato) to an area of lower concentration (the salt solution), causing the potato to lose water and shrink. This demonstrates the process of osmosis, where water moves across a semi-permeable membrane to balance the concentration of solutes on both sides.
Water moves from an area of higher water concentration (dilute solution) to an area of lower water concentration (concentrated solution) in osmosis. This movement occurs across a semi-permeable membrane.
You can place a piece of potato in a concentrated salt solution. Endosmosis will occur as water moves into the potato cells due to the higher concentration of solutes outside the cells. Conversely, placing the potato in distilled water will result in exosmosis, as water moves out of the cells to dilute the higher concentration of solutes inside the cells.
If you place a cell in a distilled water solution, water will move into the cell by osmosis causing it to swell and possibly burst. In a concentrated salt solution, water will move out of the cell causing it to shrink and potentially die due to dehydration.
Those animal cells placed in pure water will swell but plant cells are restricted by their cells walls. If place in a solution high in sugar (or even salt), both cells will shrink in a process called crenation (shriveling).

Beacause when you put the slice of potato in water osmosis takes place since concentration of water is lower then the concentration of the potato and water moves from ow concentration to high concentration so the water will move into the potato and the potato will become ridgid, But if you put salty water the salty water has a higher concentration then the potato so water will move out of the potato and the potato becomes soft.
