Potato turns blue or purple when Benedict's solution is added, indicating the presence of reducing sugars such as glucose. This color change occurs due to the chemical reaction between the reducing sugars in the potato and the copper ions in the Benedict's solution.

Why will be change in the potato cube in concentrated sugar solution and distilled water respectively after an hour?
In the concentrated sugar solution, water will move out of the potato cube, causing it to shrink due to osmosis. In distilled water, water will move into the potato cube, causing it to swell due to osmosis.
What is the reagent used for testing for reducing sugars?
Benedict's solution is a commonly used reagent for testing reducing sugars. It contains copper ions which react with reducing sugars to form a colored precipitate. The intensity of the color change can be used to estimate the amount of reducing sugars present in a sample.
What will happen to the potato when place is a concentrated sugar solution?
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).
Is mashing a potato a chemical or physical change?
Mashing a potato is a physical change because it's the same substance (the potato is still a potato) but in a different form.- - - - -Making mashed potatoes from fresh potatoes is both a chemical and a physical change: there are many chemical changes that occur when you cook a potato, and physical because it doesn't look anything like it did when you started.
Is a potato a chemical or physical change?
Cooking a potato is a physical change because it undergoes a change in form or appearance, but its chemical composition remains the same. Cooking causes the potato's starches to gelatinize and its proteins to denature, but no new substances are formed.
Why does potato turn muddy green when tested with Benedict solution?
Potato turns muddy green when tested with Benedict's solution due to the presence of reducing sugars like glucose and fructose. The reducing sugars react with the copper ions in the Benedict's solution to form a green-colored precipitate called cuprous oxide.
How Benedict's reagent solution react with potato juice?
Benedict's reagent contains copper ions which can oxidize reducing sugars present in potato juice, such as glucose and fructose. The reaction results in a color change from blue to green, yellow, orange, or red, depending on the amount of reducing sugars present. This color change indicates the presence of reducing sugars in the potato juice.
What happens when current pass throw potato?
it will change it colour
Do lettuce gelatin butter potato apple juice and oak contain sugars the sugar that use the Benedict's solution to find?
yes
A potato tuber has been cut into two halves A few drops of iodine solution are placed on the cut surface of one of the halves What colour change will be noticed?
brown dark
What liquid will best change the potato's color?
iodine solution
Why will be change in the potato cube in concentrated sugar solution and distilled water respectively after an hour?
In the concentrated sugar solution, water will move out of the potato cube, causing it to shrink due to osmosis. In distilled water, water will move into the potato cube, causing it to swell due to osmosis.
Which substance reacts with the starch grains in a potato cell and makes them more distinct in appearance?
Iodine is the substance that reacts with the starch grains in a potato cell and makes them more distinct in appearance. This reaction turns the starch grains blue-black.
What is the color of potato cell if added with iodine solution?
iodine is an indicator for starch, potatoes are basically starch storage organs for potato plants. that's why they are good to eat, mmm starch!
Is a potato a solution?
No.
Is a potato chip a solution?
Potato chips are solids.
Is potato starch a solution?
Starch is not a solution.
