Question

which of the following is considred a colloid? a. a mixture of oil and water b. a mixture of salt and iron fillings c. a mixture of soil and water d. a mixture of chalk and water

Answer 1

The correct answer is a. a mixture of oil and water. A colloid is a type of mixture where one substance is dispersed evenly throughout another substance. In the case of oil and water, the oil forms droplets that are dispersed throughout the water, creating a colloidal suspension. In contrast, the other options (salt and iron fillings, soil and water, chalk and water) do not form a colloid, as the components do not disperse evenly and remain distinct phases.
