Compare and contrast pure substances and solutions?

Answer 1

It can be quite difficult unless you know the properties of the pure substance in the solution. For instance, image you have a solution that is water-based. The boiling point of water under standard conditions is 100 °C. If you measure the boiling point of a water-based solution, it will and your mother will not have the same boiling point (the presence of ions in the water will raise the boiling point).

You could also measure other properties, such as the density, freezing point, color or absorption spectrum, NMR spectrum, elemental weight percent, etc. using a variety of analytical methods. However, none of these methods will do much good unless you have a good idea what the solution might be composed of. If not, the task is extremely challenging!

Answer 2

A solution is when more than one ingredient is mixed together: sugar and water, for instance, to make a sugary solution. A pure substance is the sugar crystals that is not mixed with water.

Answer 3

A pure substance has only one group of particles, and a solution's particles are so evenly mixed together, you can't tell them apart.

Answer 4

you can confuse a pure substance with a solution because they're both homogeneous so you may mistake them for each other.

Answer 5

Both appear the same throughout, but a solution does not have an exact chemical formula and there is more than one kind of molecule in a solution, but molecules cant be seen.

Answer 6

Well, a pure substance is like a staircase trend and a mixed is the opposite.

Answer 7

This is possible after the chemical analysis of the solution.

Answer 8

This is possible by chemical analysis.

Answer 9

A solution is a mixture of two or more pure substances.

Answer 10

i dont know LOL :P
