SUMMARY

The discussion focuses on calculating the molarity of a 37% HCl solution with a volume of 2.5L and a molecular weight of 36.46 g/mol. To determine the molarity, the specific gravity or density of the 37% HCl solution is essential, which can be found in chemical handbooks. The participants emphasize safety precautions, including the use of a pipet bulb instead of mouth pipetting and the necessity of working in a fume hood due to the hazardous nature of concentrated HCl.

PREREQUISITES
  • Understanding of molarity and molality concepts
  • Knowledge of specific gravity and its application in solution concentration
  • Familiarity with laboratory safety protocols when handling hazardous materials
  • Access to chemical handbooks for density values
NEXT STEPS
  • Research the specific gravity of 37% HCl solutions
  • Learn how to calculate molarity from mass and volume
  • Study laboratory safety practices for handling corrosive substances
  • Explore the use of fume hoods in chemical experiments
USEFUL FOR

Chemistry students, laboratory technicians, and anyone involved in preparing chemical solutions safely and accurately.

I have 1 bottle of HCL 37% Concentration with 2.5L Volume. Given the MW is 36.46g/mol. How to calculate the molarity of the HCL in the bottle? as i only need to prepare 1M of HCL?

:confused: no density and molarity given in d label
 
Physics news on Phys.org
Was that 1 MOLAR or 1 MOLAL concentration that you wanted to prepare? In case you wanted MOLAR, then you need the density or specific gravity of the HCl 37% solution. Are you permitted to look for this value in a table of values, like in a handbook?

What kind of label do you have? A professional, commercial label from a company? No matter... you can simply look for 37% HCl in a handbook to find the specific gravity of this concentration. I'm assuming that this is a laboratory task and not a question-for-credit task.
 
One more thing: since you had to ask your particular question, and it may be a practical question, DO NOT PIPET BY MOUTH. USE A PIPET BULB. In case you already know this, then please excuse this instruction, since you would use a bulb anyway.

And use a fume hood. That is above the azeotropic concentration and has a lot HCl pressure
