What is the flotation method used for?
I - Separating the components of a solid + solid heterogeneous mixture.
II - Adding a liquid with intermediate density that does not dissolve or react with the components of the mixture.
III - Separating sand and sawdust (wood shavings), for example.
IV - The sawdust stays on top of the water and the sand settles at the bottom of the container.
a) Only I and II are correct.
b) Only II and III are correct.
c) Only III and IV are correct.
d) I, II, III and IV are correct.

O método de flotação é usado para separar componentes de uma mistura heterogênea sólido + sólido. Ele envolve a adição de um líquido com densidade intermediária que não dissolve ou reage com os componentes da mistura. A mistura é agitada e os componentes mais leves flutuam na superfície do líquido, enquanto os mais pesados afundam. Portanto, a alternativa correta é a letra "a) Apenas I e II estão corretas".
