Question

Which of the following is an example of a homogeneous mixture?

a. NaOH solution

b. Mortar (mixture of water, sand and cement)

c. Vinegar and oil salad dressing

d. more than one response is correct

Answer 1

The correct example of a homogeneous mixture from the given options is a. NaOH solution, as it forms a uniform and consistent solution when dissolved in water.

Step-by-step explanation:

A homogeneous mixture is defined as a mixture that has a uniform composition and appears visually the same throughout. An example of a homogeneous mixture is a solution, where all components are dissolved uniformly. Among the provided options, a. NaOH solution is the correct example of a homogeneous mixture. This is because when NaOH (sodium hydroxide) is dissolved in water, it forms a uniform solution with the same composition throughout. On the other hand, options b. Mortar and c. Vinegar and oil salad dressing are heterogeneous mixtures, as their components are not uniformly distributed and can often be seen as distinct parts.
