Water is the solvent and chalk is the solute.
Soft water would not be considered a colloid. This is because the definition of a colloid describes it as the fine dispersion of a substance in another without a new solution forming.
Yes, suspended silt would count as a colloid.
No, it is a salt. I water it forms a solution.
Chalk particles can be collected by using a filtration process. A filter paper or a fine sieve can be used to separate the dissolved chalk particles from the water. The water can then be evaporated to obtain the solid chalk residue.
No, a mixture of chalk and water is not a colloid. A colloid is a mixture where one substance is evenly dispersed in another substance, forming a homogeneous mixture. Since chalk does not form a homogeneous mixture with water, it is not considered a colloid.
When chalk powder is mixed with water, it forms a suspension. In a suspension, the particles of the chalk powder are not dissolved in the water but rather dispersed throughout, giving it a cloudy appearance. A colloid would involve smaller particles that are evenly dispersed and do not settle out over time.
compound
Water is the solvent and chalk is the solute.
When you mix chalk with water and then evaporate the water, you are left with chalk dust or solid chalk residue. Evaporating the water removes the liquid component, leaving behind the solid chalk particles that were initially dissolved in the water.
Nothing will happen when you add water to chalk, because chalk does not dissolve in water. However, if you are drawing with chalk, as the water evaporates, it will allow the chalk to spread and create more fun.
No. Chalk is insoluble in water. Adding sugar will not change that.
An example of a solution is salt water. An example of a suspension is Italian salad dressing. An example of a colloid is mayonnaise.
No chalk is not solouble. When chalk is put in water the water becomes a suspension ie the particles of chalk keep floating in water.
yes chalk is denser then water.
Yes, the dessert Gelatin is a type of colloid. It is a colloid because it can be easily made by adding powder to water so that it congeals.
Chlorine is a gas at room temperature and pressure, not a solution or colloid. It can be dissolved in water to form a solution known as chlorine water, which is used as a disinfectant.
