Determine whether each pair of substances forms a homogeneous solution when combined. (a) ccl4 and h2o (b) kcl and h2o (c) br2 and ccl4 (d) ch3ch2oh and h2o

1) CCl₄ and H₂O:

No! Tetrachloromethane being non-polar in nature doesn't dissolve in water. Hence, when mixed they form two separate layers. Hence it doesn't give a Homogeneous Solution.

2) KCl and H₂O:

Yes! Potassium Chloride when dissolved in water ionizes to produce K⁺ ions which interacts with oxygen atom of water and Cl⁻ ions which interacts with hydrogen atoms of water. Therefore, forms a Homogeneous Solution.

3) Br₂ and CCl₄:

Yes! Bromine being non polar dissolves in non polar tetrachloromethane and forms a Homogeneous Solution.

4) CH₃-CH₂-OH and H₂O:

Yes: Ethanol and water forms Homogeneous Solution due to presence of stronger hydrogen bond interactions.
