Which of the following mixtures could be separated using the
physical property solubility?
sugar and water
gravel and vinegar
ball bearings and tennis balls
marble chips and salt
Homework Answers
The mixtures which can be separated are :
| Mixture | physical property |
| gravel and vinegar | gravel is not soluble in vinegar. These can be separated using decantation technique. |
| ball bearing and tennis balls | ball bearing and tennis balls are very different size. Ball bearings are small and tennis balls are large |
| Marble chips and salt. | Marbles chips and salt have different solubility in water. Salt is completely soluble whereas marble chips are not soluble. |
