Hard Chemistry Chapter 01: Solutions Class 12 Level 5

यदि किसी विलयन को ठंडा करने पर उसका आयतन घटता है और विलेय के मोल वही रहते हैं तो मोलरता पर क्या प्रभाव पड़ेगा?

If cooling a solution decreases its volume while moles of solute remain constant what happens to molarity?

Explanation opens after your attempt
Correct Answer

B. मोलरता बढ़ेगी / Molarity increases

Step 1

Concept

Molarity equals moles of solute divided by volume of solution.

Step 2

Why this answer is correct

If moles stay constant and volume decreases the ratio increases.

Step 3

Exam Tip

Therefore molarity increases. चरण 1: मोलरता विलेय के मोल बटे विलयन का आयतन है। चरण 2: जब मोल समान रहें और आयतन घटे तो भागफल बढ़ता है। चरण 3: इसलिए मोलरता बढ़ेगी। ताप संबंधी प्रश्नों में आयतन परिवर्तन पर ध्यान दें।
