7.A Ions in Solution

Solutions are homogeneous (completely mixed) mixture of 2+ compounds in a single phase (whether it be solid/liquid/gas). Solutions in liquid are most well known, but are possible in other phases too. For example, brass is a solid solution of zinc and copper.

“My favorite solution is the ice coffee,” Miley says.

“Yes, a nice mix of coffee beans, sugar, water, milk… but it’s likely it’s not a perfect example of a solution, though; there’s likely to be a suspension and sediments.”
