Question

A sample of a salt and water solution is homogeneous throughout. Is this sample a mixture or a pure substance?

A. A mixture, because it can have a variable composition
B. A pure substance, because it has a definite composition
C. A mixture, because it has a fixed, definite composition

Answer 1

A

Answer 2

A...

Answer 3

Wouldn't it be C since the mixture is homogenous?

Answer 4

mixture can be homogeneous or non homogeneous........but it doesnt meam it is pure substance...in pure substance every atom/ molecule in it is same....u cant differentiate betn them...eg in the pure salt every molecule is NaCl but in mixture u can differentiate betn them eg in salt water mixture u can differentiate bet molecule of salt NaCl and molecule of water H20.....

Answer 5

Then it wouldn't be called a mixture...In my opinion.
I believe it's C because a homogenous mixture has the same composition, or density, of molecules everywhere.

Answer 6

As in the salt isn't concentrated in one spot, but equally dissolved.

Answer 7

You're basically explaining that all mixtures are heterogenous.

Answer 8

A
