Re: Calver II indicator, Is there another name ,How to locate?

Sorry, I can only give you an educated guess.  This sounds like the trade 
name for a mix of an indicator and Versene (TM), which is EDTA.  
I would suggest titrating for calcium with Calmagite (1-[1-hydroxy-4-
methyl-2-phenylazo]-2-naphthol-4-sulfonic acid) with the addition of 
EDTA.  I don't have any methods handy just now, but you may be able to 
search under the CAS numbers for the free acid [3147-14-6] and the 
triethanolammonium salt [91698-30-5] and come up with an appropriate 
method.
