Iron powder will not dissolve in water. It remains as solid particles suspended in water, forming a mixture known as a suspension.
When a powder is dissolved in water, the resulting mixture is called a solution. If the powder is a solid solute, the water acts as the solvent. The solute is evenly distributed within the solvent, creating a homogeneous mixture. Examples include sugar or salt dissolved in water.
To separate a mixture of table salt and talcum powder, you can use water as a solvent. Dissolve the salt in water, which will not affect the talcum powder, then filter the mixture. The salt will pass through the filter paper into the filtrate, while the talcum powder will remain on the filter. Finally, you can evaporate the water from the salt solution to obtain pure salt.
Water and insoluble powder will result in a suspension, where the particles of the powder are dispersed throughout the water but do not fully dissolve. This creates a mixture where the powder may settle at the bottom over time if left undisturbed.

If the powder is totally soluble the solution is homogeneous.

Table salt can be separated from a mixture of table salt and talcum powder through a process called filtration. In this process, the mixture is dissolved in water, allowing the salt to dissolve while the talcum powder remains insoluble. The mixture is then passed through a filter, which separates the insoluble talcum powder from the salt solution. The salt can then be recovered by evaporating the water, leaving behind the pure salt crystals.
No. Oobleck is a mixture of corn starch and water.
When iron powder and salt are added to water, the iron powder will react with the water to produce iron oxide (rust), hydrogen gas, and heat. The salt will dissolve in the water. This reaction is a chemical change, resulting in a mixture of iron oxide, hydrogen gas, salt solution, and any unreacted iron powder.
Water mixes with powder due to a process called wetting and dispersion. The water molecules break down the intermolecular forces between the particles in the powder, allowing them to spread out and dissolve or form a suspension. This process helps create a uniform mixture of water and powder.

One way to separate cocoa powder from water is through filtration. Place the cocoa powder and water mixture in a filter, such as a coffee filter or cheesecloth, and allow the water to pass through while retaining the cocoa powder. Another method could be to let the mixture settle, allowing the cocoa powder to sink to the bottom, and then carefully decanting the water from the top.
