1. State one property in which a solution of sugar in water resembles a mixture of sugar and sand, and one property in which it differs from it?
sugar in water and sugar in sand: both contain sugar.
sugar dissolves in water; sugar does not dissolve in sand.
sugardissolve in watet ,does not disolve in sand
Solution of sugar in water resembles a mixture of sugar and sand in terms of being a homogeneous mixture. Both the sugar-water solution and the mixture of sugar and sand appear uniform throughout.
However, the two differ in terms of their ability to be separated. A sugar-water solution can be easily separated using physical methods, such as evaporation or filtration, whereas a mixture of sugar and sand cannot be easily separated by such methods.
To determine a property in which a solution of sugar in water resembles a mixture of sugar and sand, and another property in which it differs, we need to understand the nature of both a solution and a mixture.
1. Resemblance: In both cases, sugar and water solution and a mixture of sugar and sand are both heterogenous mixtures. This means that they consist of two or more substances physically combined without forming new chemical bonds. Both sugar solution and sugar sand mixture can be separated through physical methods, such as filtration or evaporation.
2. Difference: The key property that differentiates a solution of sugar in water from a mixture of sugar and sand is the level of uniformity or homogeneity. A sugar and water solution is a homogeneous mixture, which means that the sugar particles are dissolved uniformly throughout the water. On the other hand, a mixture of sugar and sand is heterogeneous, where the sugar and sand particles are physically mixed but not dissolved. In the sugar and sand mixture, you can easily identify the separate particles of sugar and sand by their appearance and texture.
In summary, the key difference lies in the homogeneity and separation techniques. The sugar solution appears uniform throughout, requiring a different separation technique like evaporation, while the sugar and sand mixture remains visually separate and requires techniques like filtration to be separated.
