When you dissolve sugar in water to make lemonade, you are creating a Solution. In Class 9 Chemistry (Is Matter Around Us Pure?), understanding the two components of a solution — the Solute and the Solvent — is the first step.
Water is called the Universal Solvent because it can dissolve more substances than any other liquid on Earth!
Solution = Solute + Solvent
When salt is dissolved in water → Salt is the solute, Water is the solvent, and the resulting salt water is the solution.
Solutions are not just liquid! Based on the state of solute and solvent:
Yes. When two liquids dissolve in each other (like ethanol and water), the one present in *larger* quantity is the solvent.
Difference Between Ideal and Non-Ideal Solution
Understand the difference between ideal and non-ideal solutions in Class 12 Chemistry. Learn about Raoult's law, enthalpy, and volume changes upon mixing.
Inner Transition Elements — f-Block Elements
Learn about inner transition elements (f-block). Understand what lanthanides and actinides are, their position in the periodic table, and their key properties.
What is the Valency of Iodine?
Learn the exact valency of the element Iodine in Chemistry. Understand why it has a primary valency of 1 and how it forms massive compounds like KI.
Ionisation Enthalpy — Definition, Periodic Trends and Anomalies
Ionisation enthalpy is the energy needed to remove one electron from a gaseous atom. It increases across a period and decreases down a group. Learn trends and anomalies with FAQs.
What is the Iron-Carbon Phase Diagram?
Understand the basics of the Iron-Carbon phase diagram. Learn about austenite, ferrite, cementite, and how carbon content transforms iron into steel.
