compound
Yes, mouthwash is a colloid. It is a liquid mixture containing suspended particles that do not settle out.
HCl is a solution, not a colloid or suspension. A solution is a homogeneous mixture where one substance dissolves in another, as is the case with HCl dissolved in water. Colloids are mixtures with particles dispersed throughout, while suspensions have particles that can settle out over time.
The order from smallest particle size to largest particle size is: solution (smallest), colloid, suspension (largest).
Hot chocolate is a colloid. It is a mixture where small particles of chocolate or cocoa are dispersed throughout a liquid (milk or water) to form a stable mixture.
Salt and pepper are considered a mixture, not a solution or a colloid. In this case, salt and pepper are mechanically mixed together, but the individual components do not dissolve into each other or form a stable suspension.
Colloid has larger particles compared to solution, but smaller than suspension. Therefore, of the three options listed (compound, colloid, suspension), a compound mixture typically has the smallest particles.
A colloid is not a single compound; it is a mixture with properties between those of a solution and fine suspension.
Suspension
Sand is a mixture and rarely is only one compound.
suspension
compound
A colloid.
Yes, mouthwash is a colloid. It is a liquid mixture containing suspended particles that do not settle out.
heterogenous
HCl is a solution, not a colloid or suspension. A solution is a homogeneous mixture where one substance dissolves in another, as is the case with HCl dissolved in water. Colloids are mixtures with particles dispersed throughout, while suspensions have particles that can settle out over time.
Salt is a compound because it is composed of sodium and chloride ions that are chemically bonded together in a fixed ratio. It is not an element, suspension, heterogeneous mixture, homogeneous mixture, or colloid.
The order from smallest particle size to largest particle size is: solution (smallest), colloid, suspension (largest).
