in BR chemistry, chapter 1... they use the term hydroscopic to refer to a hydroscopic salt that soaks up H2O and doesnt react with CO2.

what does hydroscopic mean? when i looked it up this is what i found...


The word is misspelled and therefore has no definition. The spelling is hygroscopic.
The definition of hygroscopic is: readily taking up and retaining moisture.
The definition is from Webster's New Collegiate Dictionary.


is hydroscopic the wrong word? there is also a passage in BR concerning this concept.

I've heard people use either, although I understand that "hygroscopic" is the correct version. Hygroscopic compounds normally need to be kept in a dessicator, or carefully sealed away from the atmosphere to prevent them taking up too much water.

I have a 2003 copy with that typo and a Summer 2010 copy without that typo, so I'm not sure when it was removed. Because you mentioned that typo, I assumed you had the 2003 book I was looking at. If you ordered it from BR in the last year, then you have the latest version.
