Trying It Together You have samples of urea (a solid at room temperature) and pure ethanol (a liquid at room temperature). Which technique or techniques would you use to measure the amount of each substance? |
Explanation
Urea is a solid so it's amount can measure in mass units like Kg, g, mg etc. For urea the the use of urease to enzymatically catalyze the hydrolysis of urea, followed by detection of ammonia by colour reactions or electrochemical techniques apart from this simple weighing is also an option.
Ethanol is a liquid so it's amount can measure in volume units that are mL, L, dm3 , m3 ,etc. For ethanol measurement we can use Distillation, Ebulliometry, Hydrometry, Refractometry.
Verified Answer
Urea(solid) = mass unit
Ethanol (liquid) = volume unit
