    Difference
In summary, the conversation is about the terms used to describe a mixture of TiO2 suspended in water. The terms "colloidal solution" and "slurry" are both used, and the question is whether or not they are synonyms and which one is the correct term. The clarification is needed because Google searches have not provided a clear answer.

A little clarification on this? I'm working with TiO2 suspended in water. Its a mixture of both rutile and anatase phase TiO2, and I've heard people refer to it as a colloidal solution and a slurry. Are they synonyms? Is one an incorrect description? Are they not synonyms, but both correct in a different way?

Any clarification would be helpful. Google-ing hasn't been helpful in clearing this up for me.

Slurry is particulates suspended in solution. The suspension may require agitation to maintain the particles in suspension. Colloidal suspension indicates those particles are small and little to no agitation is required to keep them that way.
 

1. What is the main difference between a colloidal solution and a slurry?

A colloidal solution is a mixture where one substance is dispersed evenly throughout another substance, while a slurry is a mixture of a solid and a liquid where the solid particles are not completely dissolved and may settle over time.

2. How can you tell if a mixture is a colloidal solution or a slurry?

The main difference between a colloidal solution and a slurry is the size of the particles. Colloidal particles are smaller than 1 micrometer and do not settle, while slurry particles are larger and can settle over time.

3. What are some common examples of colloidal solutions and slurries?

Colloidal solutions can include milk, mayonnaise, and paint, while slurries can include cement, mud, and clay.

4. Can a substance be both a colloidal solution and a slurry?

Yes, some mixtures can exhibit properties of both colloidal solutions and slurries. For example, some mud can have both colloidal particles and larger solid particles that settle over time.

5. How are colloidal solutions and slurries used in different industries?

Colloidal solutions are commonly used in the food industry for products like sauces and dressings, while slurries are used in construction for cement and drilling fluids in oil and gas extraction.
