         i am business man. i am manufacture in calcite powder . my new buyer want  "63% calcium content and easy soluble in water". but don't have no idea. please Any one give a good idea for me or how is convert caco3  soluble in  water? please friend's it's very useful for me

CaCO₃ is insoluble and contains around 40% of calcium. Your customer could as well ask for a light lead or white coal, would make about as much sense.

Are you sure he is not asking for a burnt lime?

my buyer use for my material  just like fertilizer and want more calcium content. he check my product it's have 97.5 to 98.8 % of calcium. he know it's not soluble. but he ask add any elimination content add with your product and make it soluble.  i have ask to him i will add nitrate it's get ca(no3) . but he say it will some exporting trouble for your country(India). so i want how i make it?

You can't do the impossible.

oh OK thanks  sir

he check my product it's have 97.5 to 98.8 % of calcium.

That's almost pure calcium - which is a highly reactive metal. As I wrote earlier, calcium in CaCO₃ is about 40% by mass. Whole thread is riddled with confusion.

Ok, one tip: Do use Capital letters and punctuation when you post. It helps.

YES I KNOW BUT IT'S OUR BUSINESS LANGUAGE . BECAUSE CA(MG)CO3(DOLOMITE) ALSO SELL IN MY MARKET SO WE EASY WAY TO HIGHLIGHT OUR PRODUCT AT CALCIUM % SEE MY ATTACHMENT

Sigh, apparently you can use either capital letters only or small letters only, no positions between.

You need to define what your "business language" really means in chemical terms then. Still it sounds like you are asking impossible.

Law of unintended consequences. 

Apologies; I guess I made things worse here, eh?
