Which of following statement(s) is/are true?
i. A mixture contains particles of two or more pure substances, which may be present in it in any ratio.
ii. Sugar solution and air are the examples of homogeneous mixtures.
iii. Mixtures of salt and sugar, grains and pulses along with some dirt (often stones), are heterogeneous mixtures.
-
A.
i, ii and iii
-
B.
ii and iii only
-
C.
i and iii only
-
D.
i and ii only
Correct Answer:
A. i, ii and iii
Explanation:
All three statements are correct regarding the nature of mixtures. A mixture consists of two or more pure substances combined in any proportion without a chemical reaction. In a homogeneous mixture, like a sugar solution or air, the components are distributed uniformly throughout, making the composition consistent. Conversely, a heterogeneous mixture, such as a combination of salt and sugar or grains mixed with dirt and stones, has a non-uniform composition where the individual components remain physically distinct and can often be seen separately.
