Let's analyze the contents of both beakers to determine the nature of the final substances they form.
Beaker X:
- Contains sugar and water.
- When sugar is added to water and is not visible, it indicates that the sugar has dissolved completely in the water.
- The result is a homogeneous mixture known as a solution, where the solute (sugar) is uniformly distributed within the solvent (water).
Beaker Y:
- Contains sand and water.
- When sand is added to water, it does not dissolve and instead settles at the bottom.
- This indicates a heterogeneous mixture, where the components can be visibly distinguished, and the mixture is not uniform throughout.
Given these observations:
- The final substance in Beaker X is a solution, which is a type of mixture since it consists of multiple components (sugar and water) combined physically.
- The final substance in Beaker Y is a suspension, which is also a type of mixture as it consists of sand particles dispersed in water.
Both of these beakers contain mixtures because they are composed of multiple substances combined together physically and there is no formation of a pure single substance.
The correct statement is:
a) The final substances in both the beakers are mixtures.
This completes the detailed step-by-step solution confirming that both beakers form mixtures.
