Medium Chemistry Chapter 01: Solutions Class 12 Level 9

बारीक पिसा हुआ विलेय जल्दी घुलता है लेकिन अंतिम विलेयता क्यों जरूरी नहीं बदलती?

Why can a finely powdered solute dissolve faster without necessarily changing final solubility?

Correct Answer

A. सतह क्षेत्र दर बढ़ाता है पर संतृप्त मात्रा ताप पर निर्भर रहती है / Surface area increases rate but saturated amount depends on conditions like temperature

Step 1

Concept

Smaller particles have larger surface area.

Step 2

Why this answer is correct

They dissolve faster, but maximum dissolved amount at a fixed temperature usually remains the same.

Step 3

Exam Tip

Dissolving faster and dissolving more are different ideas. चरण 1: छोटे कणों का सतह क्षेत्र अधिक होता है। चरण 2: वे जल्दी घुलते हैं लेकिन निश्चित ताप पर अधिकतम घुली मात्रा सामान्यतः वही रहती है। चरण 3: तेजी से घुलना और अधिक घुलना अलग बातें हैं।
