Which is NOT a solution? 1 metal alloys, 2 ice in water, 3 sugar in water, 4 vinegar in water.......the answer is ice in water correct?
Right, unless we stretch the rules.
To determine which option is NOT a solution, you need to understand what a solution is. A solution is a homogeneous mixture composed of two or more substances, where one substance is dissolved in another. The substance that is dissolved is called the solute, and the substance in which the solute is dissolved is called the solvent.
Now, let's analyze the given options:
1) Metal alloys: Metal alloys are homogeneous mixtures of two or more metals. They form solid solutions since the different metals are dispersed uniformly at the atomic level.
2) Ice in water: When ice is added to water, it melts and dissolves into the water, forming a homogeneous mixture. In this case, the ice is the solute, and water is the solvent. Therefore, ice in water is a solution.
3) Sugar in water: When sugar is added to water, it dissolves and forms a homogeneous mixture. Sugar acts as the solute, and water acts as the solvent. Therefore, sugar in water is a solution.
4) Vinegar in water: Vinegar is an aqueous solution of acetic acid, which means it is already a solution. When vinegar is mixed with water, it further dilutes the acetic acid in water. Therefore, vinegar in water is also a solution.
Based on the above analysis, the option that is NOT a solution is ice in water.
