1. Milestone has developed an innovative, pure unbuffered 10% EDTA solution, based on a stoichiometric mixture of Bibasic or tribasic EDTA to reach this pH value without the addition of an acid/base buffer.

2. Boric acid, also called hydrogen borate, boracic acid, and orthoBoric acid is a weak, monobasic Lewis acid of boron.However, some of its behaviour towards some chemical reactions suggest it to be tribasic acid in the Brønsted sense as well
