What substances are responsible for the different colors of the solution after the iodine test?
The iodine test primarily detects the presence of starch. When iodine (I₂) interacts with starch, it forms a blue-black complex due to the helical structure of amylose. If there are no starches present, the solution may remain yellow-brown, which is the color of iodine in water. Other substances, such as proteins or sugars, may also influence the color but do not produce the characteristic blue-black color associated with starch.

Why do the colours in rainbow fizz change?
The colors in rainbow fizz change because of the interaction between the different compounds in the fizzing solution, which can create a variety of chemical reactions that produce distinct colors. Each color is associated with a specific chemical process occurring in the solution, leading to the changing colors as the reaction progresses.
What are the photoreceptors that do not distinguish different colors?
Rod cells are photoreceptors that do not distinguish different colors. They are highly sensitive to light and are primarily responsible for vision in dim light conditions. Rod cells do not contain the pigments necessary to perceive different colors, so their function is more focused on providing black and white vision.
How colorful mixtures works?
Colorful mixtures work by combining different colored substances or pigments in various proportions to create new colors. This is based on the principle of color mixing, where different colors can be combined to produce a wide range of hues. By blending colors together, we can create visually appealing and diverse color combinations.
What is the meaning of the different colors in Benedict's test?
The different colors in Benedict's test represent the varying levels of reducing sugars present in a solution. A blue color indicates no reducing sugars present, while green, yellow, orange, and red colors indicate increasing levels of reducing sugars, with red being the highest concentration.
What substances are in variegated leaves?
Variegated leaves may contain pigments such as chlorophyll, carotenoids, and anthocyanin in varying amounts. These pigments contribute to the different colors seen in variegated leaves. Additionally, variegated leaves may have varying levels of starch, sugars, and other nutrients depending on the plant species.
Why are there colors on planets?
For the same type of reason there are colors here on Earth. That's because different substances react differently to light.
What is the change that happened in each of the colors how?
When two or more substances combine, they create one or more new substances, which sometimes have different molecular structures from the original substances, meaning they absorb and radiate light in different ways, leading to a color change.
What causes the different color variations in ocean water?
The different color variations in ocean water are caused by the presence of various substances such as phytoplankton, sediments, and dissolved organic matter. These substances can absorb and scatter light, leading to different colors in the water.
What causes people to see different colors?
People see different colors due to variations in their eyes' cone cells, which are responsible for detecting colors. Additionally, differences in lighting conditions, the way light is processed by the brain, and individual perception can also influence how colors are perceived.
Two similar looking substances are burned one produces a red flame the other produces a yellow flame this is an example of?
Chemical properties being responsible for the color of flames. The specific atoms present in each substance result in different colors when they undergo combustion.
Why are houses and buildings constructed with different designs and colors?
Design and colors is responsible for the beauty of houses. No body requires houses of a same design to other because everyone wants houses whose design are unique and different from other houses. That's why, houses and building constructs with different designs and colors.
Why light is dispersed by a prism?
Light is dispersed by a prism because it consists of different colors with different wavelengths. When light enters a prism, it changes speed and is refracted at different angles based on its wavelength, causing the colors to spread out. This dispersion is responsible for the rainbow of colors seen when white light passes through a prism.
Which property most easily distinguishes sulfur from the other solid substances?
Sulfur has a distinct bright yellow color, which easily distinguishes it from other solid substances that may be colorless or have different colors.

Can bases be classified with an indicator?
Yes. There are many different types of indicators that change colors at different levels of pH. While it will depend on you concentration of base. You can use it indicate if a solution is basic, and narrow down the actual species in solution.
Why do flames change colors?
Well simple, It's similar to the way light changes colors when it's refracted through different materials, such as a rainbow. After rain, the sunlight is bent through the humid atmosphere causing colors. same with fire, different substances used in its firelighter (aka Ligherfluid) change colors of the flame itself
