Salt is stirred into water until nothing separate can be seen anywhere in the glass. What kind of mixture is this?

1. Mixtures split into two families depending on whether the parts can be told apart. 2. A homogeneous mixture is uniform and its different components cannot be seen. 3. Soil is the opposite case, since pebbles, sand and plant matter can all be picked out. 4. That opposite case is called a heterogeneous mixture. _Source: Siyavula Physical Sciences Grade 10 (Everything Science, CC BY 4.0), Chapter 2: Classification of matter_
