If you answer these 2 questions right then i will mark you brainlist please give right answer.
1.Hari took a glass containing water and mixed it with a spoonful of salt into it initially. He observed that the salt dissolved completely. He kept on adding the salt till he observed that no more solute is dissolved in the solvent.
a.Was there any change in water level in the glass initially? Justify.
b.Why did the salt remain undissolved at last?
2. Identify whether an open carbonated drink is a homogeneous or heterogeneous mixture. Justify your answer.
Answers
Explanation:
The change in volume is so minute that it is negligible because the water molecules are loosely packed, they have spaces between them. When salt is dissolved, it will occupy those spaces. Thus, no change in level of water
Explanation:
1)
a)There won't be any change in the water level because water molecules a loosely packed they have space between them and when salt dissolves in water, the salt particles occupy the distance between the water molecules. Hence the water level won't change.
b)When you dissolve salt into a glass of water it completely dissolves. You add a couple more spoons of salt in the water until it stops dissolving because it becomes a saturated solution.
Meaning of Saturated Solution: A solution in which no more solute can be dissolved at a particular temperature is called a saturated solution.
2)
The amount of every ingredient is fixed. All the components such as sweetener, water, carbon dioxide bubbles are all evenly distributed. Such mixtures in which the amount of every component is uniform are termed homogenous mixtures. Hence, the carbonated beverage is a homogenous mixture.
P.S These answers were from my notes plz don't mistake!
