No, carbon tetrachloride (CCl4) will not sink in sulfuric acid (H2SO4).

Here's why:

* Density: Carbon tetrachloride has a density of 1.59 g/mL, while sulfuric acid has a density of 1.84 g/mL. This means sulfuric acid is denser than carbon tetrachloride.

* Immiscibility: Carbon tetrachloride and sulfuric acid are immiscible, meaning they do not mix.

Therefore, carbon tetrachloride would float on top of sulfuric acid.
