Matter Around Us Pure? is the chapter 2 of Class 9 NCERT book. The Multiple Choice Question (MCQ) Question is given below for Class 9 Chapter 2 Is Matter Around Us Pure?
Which of the following is a True Solution?
(b) Vinegar Solution
(c) Muddy Water
Option (b) is the right answer.
Vinegar solution is an acetic acid solution. It dissolves in water and gives a true solution.
Q 1: What is a True Solution?
Ans: A true solution is a homogeneous mixture with consistent properties. Filtration cannot separate the solute from the solution in a true solution. The solute’s particle size is around the same as the solvent’s, and the solvent and solute move through the filter paper together.
A true solution is a homogeneous mixture of two or more substances in which the particle size of the material dissolved (solute) in the solvent is less than 10-9 m or 1 nm. True solution is exemplified by a simple sugar solution in water.
Q 2: What are the properties of True Solution?
A true solution is a mixture of solute and solvent that is homogeneous. Filtration cannot separate the solute from the solution in a true solution. The solute’s particle size is around the same as the solvent’s, and the solvent and solute move through the filter paper together.
Q 2: Is milk a true solution?
Ans: No, milk is not a true solution.
Q 3: Why Milk is not a True Solution?
Ans: Milk isn’t a solution because it has two phases suspended within it: a liquid phase and a solid phase. Since fat is less dense than water, it separates from the rest of the milk and rises to the surface, making homogenized milk a suspension rather than a solution.
