Would the iodine solution change colour when it is tested on a slice of bread?
No, iodine solution will not change color when tested on a slice of bread. Iodine solution reacts with starch, turning it blue-black. Bread does not contain starch in high enough amounts to produce a noticeable color change.
What happens when a slice of lemon is put into a glass ice tea?
The lemon slice adds a burst of citrus flavor to the iced tea, enhancing its overall taste. It can also provide a refreshing and slightly tangy contrast to the sweetness of the tea. Some people enjoy the aesthetic appeal of the lemon slice floating in the glass as well.
Which way would the water molecules move in a cucumber slice in salt water?
Water molecules would move out of the cucumber slice and into the salt water by the process of osmosis. This is because the concentration of salt is higher in the salt water, causing water to move from an area of higher concentration (inside the cucumber slice) to an area of lower concentration (the salt water).
Is a slice of cheese a homogeneous mixture?
Yes, a slice of cheese is a homogeneous mixture because it has a uniform composition throughout. The different components of cheese, such as proteins, fats, and water, are evenly distributed in the slice, making it a homogeneous mixture.
How big is 14 grams?
14 grams is equivalent to approximately 0.5 ounces, or about the weight of a slice of bread.
Would the iodine solution change colour when it is tested on a slice of bread?

How do you test for starch in potato extract?
Use concentrated Iodine, If parts of the potato turn blue-black, there is starch present.=Be careful - iodine is an irritant.==OBVIOUSLY, Don't eat the potato afterwards!=
What happens to a potato slice placed in a Petra dish in fresh air?
The potato slice will wilt and turn brown.
What structures of a potato cell are stained by iodine?
the structures that are stained with the iodine are bean shaped organelles called leucoplasts.
Does potato slice have starch?
yes
What happens to a potato slice in a solution of water that demonstrates osmosis?
the potato slice with decrease in mass, as the free water molecules during osmosis will leave the potato paasing through the semi permeable membrane. This happens because there is more free water molecules on the outsite of the potato, forcing more net movement towards the outside of the potato
What happens if a potato slice is placed in tap water?
If a potato slice is placed in tap water, the potato will absorb water through the process of osmosis. This causes the potato cells to swell and the slice to increase in size. The potato slice may also become softer due to the increased water content.
How can I slice potato wedges?
To slice potato wedges, first cut the potato in half lengthwise, then cut each half into wedges by cutting diagonally. Coat the wedges in oil and seasonings, then bake or fry until crispy.
What is a thin slice of potato called?
If the thin slices of potato are deep fried, they are known as 'crisps' in the UK.
Does slice of potato contain water?
no.it contains starch...
A potato slice when placed in water for several hours will become very stiff because?
the water absorbed by the potato slice through osmosis causes its cells to swell and become turgid, increasing the rigidity of the slice. This process, known as turgor pressure, gives plants and plant-based foods their structure when they absorb water.
How does the process of osmosis affect a potato slice that is saturated with water?
Osmosis is the movement of water molecules across a semi-permeable membrane from an area of high concentration to an area of low concentration. When a potato slice is saturated with water, it means that the cells in the potato have absorbed as much water as they can hold. In this state, osmosis will not have a significant effect on the potato slice because there is no concentration gradient for water to move across the membrane.
