What is henry's law class 12?

Hey! As a Class 12 chemistry tutor, I can break down Henry’s Law for you. It’s a key concept in the Solutions chapter, dealing with how gases dissolve in liquids. Henry’s Law states that the solubility of a gas in a liquid is directly proportional to the partial pressure of that gas above the liquid at a constant temperature. In simpler terms, more pressure on the gas means more of it dissolves in the liquid.Mathematically, it’s:S = k × P- S = solubility of the gas (mol/L)- k = Henry’s Law constant (specific to the gas and liquid)- P = partial pressure of the gas (atm)Example: In soda bottles, carbon dioxide (CO₂) is dissolved under high pressure. When you open the cap, pressure drops, and CO₂ escapes as bubbles. It’s super relevant for things like scuba diving or industrial processes. For more, check: NCERT Solutions on Henry’s Law.

Hi! I remember sweating over Henry’s Law in Class 12, so let’s make it simple. It’s about how much gas can dissolve in a liquid—like oxygen in water or CO₂ in your Coke. The law says: the amount of gas dissolved is proportional to the pressure of that gas above the liquid, as long as temperature stays constant.Formula: S = kP- S is how much gas dissolves.- k is a constant (depends on the gas and liquid).- P is the gas’s pressure.Think of a fizzy drink: high pressure keeps CO₂ dissolved; pop the cap, and it fizzes out. It’s key for CBSE exams, so practice numericals! This site explains it well: Byju’s on Henry’s Law.
