Which solution is a homogeneous mixture?
avanturin [10]

salt and water solution is a homogeneous mixture

<u>Explanation:</u>

Homogeneous mixtures generally termed as solutions, have an identical similar occurrence and form throughout (the prefix "homo" means the same). Solutions consist of particles as tiny as fragments or molecules. For instance, a sugar solution is homogeneous because only transparent liquids can be seen. Homogeneous mixtures only have individual phase: gas, liquid or solid.

Solvent: normally the material in the greater amount. The material used to dissolve the solute or solutes. Example: water.

Solute: ordinarily the substance in the lesser amount. The substance dissolved by the solvent. Example: salt

Salt and water solution is homogeneous because only transparent liquids can be seen.
