Re: help me on my coursework please!! (hardness of water) (Mr. Confused)

Look up the definition of "hardness." Titrate a known volume of water with standardized soap solution. When you get foam you know the hardness of the aliquot - at worst with a unit conversion.

How do you know the titrant is properly stanardized?

You haven't attended lecture nor have you cracked your textbook. I doubt you could find the department or campus library with a map. You haven't worked Google.

There are people too lazy to think and people too stupid to think. That is why there are failing grades. Save the drama for your mama. Get down and push.
