غلظت محلول

   نوشته شده توسط: امین صادقی    

برای یک محلول معین ، مقدار ماده حل شده در واحد حجم حلال یا در واحد حجم محلول را غلظت ماده ی حل شده میگوییم. مهم ترین نوع غلظت ها که در آزمایشگاه به کار میرود مولاریته و نرمالیته است.

مولاریته عبارت است از تعداد مول های یک ماده که در یک لیتر محلول وجود دارد ، به همین دلیل واحد آن را مول بر لیتر یا M/L میگیرند.

نرمالیته یک محلول عبارت است از تعداد هم ارز گرم های ماده موجود در یک لیتر که آن را با N نشان میدهند.
