When cassava starch is mixed with water, it creates a milky, opaque suspension that appears slightly cloudy and viscous. The starch particles disperse in the water, giving it a thicker consistency than plain water. Depending on the concentration of the starch, the mixture can range from a thin slurry to a more gel-like form. Overall, it has a glossy, smooth appearance.

Why is there starch in water?
Starch in water may occur during cooking when starch-containing foods are rinsed or soaked in water. Starch granules can release into the water due to mechanical action or heat, resulting in a cloudy appearance to the water.
How do you make chalk from cassava starch?
yes absolutley i am a teacher my self and it works beautifully mate ok well good luck though if your using it with little kiddes then mind you i would use white borad marker in stead (ON A WHITE BOARD)
What is the procedure n making chalk using cassava?
To make chalk using cassava, first, the cassava roots are peeled, washed, and then grated or ground into a pulp. The pulp is then mixed with water and allowed to settle, separating the starch from the fibrous material. The starch is collected, dried, and then processed further, often by mixing it with calcium carbonate or other fillers to achieve the desired chalk consistency. Finally, the mixture is shaped into sticks or powder and allowed to dry completely before use.
Is starch dissolve in water and why?
Starch consist of two types of natural polymers.NamelyAmylopectinAmyloseAmylopectin is water soluble but Amylose is water insoluble.this is reason why starch don't dissolve in water
Is the soaking water of cassava poison?
Yes, the soaking water of cassava can be toxic because it may contain cyanogenic compounds that release cyanide when cassava is not properly processed. To make cassava safe for consumption, it should be peeled, soaked, and cooked thoroughly to reduce these toxic substances. It is crucial to discard the soaking water to avoid any risk of poisoning. Proper preparation is essential for safe consumption.
Is dissolving starch in water physical or chemical change?

Is starch gelatinization a chemical or physical change?
Starch gelatinization is a physical change because it involves the rearrangement of starch molecules in the presence of heat and water to form a gel-like structure without undergoing any chemical reactions.
What are three physical properties of corn starch?
Three physical properties of corn starch are its granular structure, solubility in water, and texture. Corn starch appears as fine, white granules that can absorb moisture and swell when heated in water, forming a gel-like consistency. It is insoluble in cold water but dissolves in hot water, which is essential for its thickening properties in cooking and food production. Additionally, corn starch has a smooth, powdery texture, making it useful as a thickening agent and anti-caking agent in various applications.

Does H2O contain starch?
No. Water contains nothing but water. It can contain starch if starch is added to it.
How is tapioca made and what are the steps involved in the process?
Tapioca is made from the cassava root. The root is peeled, washed, and grated to extract the starch. The starch is then dried and processed into small pearls or flakes. These pearls or flakes are then cooked in water until they become translucent and soft, resulting in tapioca pudding or other tapioca-based dishes.
How could you explain that the change that take place in when salt is added to water is physical change?
It is a physical change because when salt is added to water,it is dissolved in it which only changes its physical appearance.
How can cassava tubers be preserve for some days before using them for flour?
