SOLUTIONS

Class 12(Chemistry), Chapter-1.

What are the types of solutions(with examples)

Define the following:
1. Solution
2. Homogeneous mixture(its geneous; not genous)
3. Binary solution
4. Solvent
5. Solute.

• Solution: A homogeneous mixture of two or more components.

• Homogeneous Mixture: A mixture where composition and properties are uniform throughout.

• Binary Solution: A solution consisting of only two components.

• Solvent: GENERALLY, the component present in the largest quantity. It determines the physical state of the solution.

• Solute: One or more components present in the solution other than the solvent.

What’s the state of the solution if the solvent is:
1. solid
2. liquid
3. gas

Answers:
1. solid
2. liquid
3. gas

Note: The physical state of the solvent always dictates the physical state of the final solution. If the solvent is a gas, the solution is also a gas, regardless of the solute.

Bro, what’s Henry’s Law.

Confusing Version:

"The partial pressure of the gas in the vapour phase (p) is proportional to the mole fraction of the gas (x) in the solution."

Plain English Version:

"The pressure of the gas ABOVE the liquid is directly linked to how much of that gas is DISSOLVED IN the liquid."

Or even simpler:

"More pressure above → More gas dissolves inside"

What are the 3 applications of henry’s law.

NCERT page no.8. class 12 chemistry part 1

Whats Partial Pressure
also, whats dilution threshold from molefraction

molefraction(x of solute)
x < 0.01 - Dilute
x > 0.01 - Non-dilute

What’s the vapour phase?

and, whats volatile and non volatile.

Volatile: Easily evaporates. High vapour pressure
non-volatile: opposite of volatile, duh.

State Raoult’s Law
State Dalton’s law of partial pressures

the answer of dalton stuff is in page no. 10 ncert
