Question

find the normality of hlc solution containing 0.0365g/ml​

Answer 1

Answer:

WELL, let us see…

Normality here is the same proposition as MOLARITY, moles per unit volume…and we work from a volume of one millilitre volume of acid that contains a 0.0365∙g mass of HCl ,

And thus Concentration=Moles of soluteVolume of solution

I am tempted to leave the answer there, and let you do the arithmetic, but since it is Xmas…we take…

[HCl]=0.365∙g36.50∙g∙mol−1moles of solute×11×10−3∙Linverse volume of solution=10∙mol∙L−1

The conc. hydrochloric acid that we use in the lab is approx. 10∙mol∙L−1.

Answer 2

Answer:

Normality here is the same proposition as MOLARITY, moles per unit volume…and we work from a volume of one milliliter volume of acid that contains a 0.0365∙g mass of HCl ,

And thus Concentration=Moles of solute Volume of solution
