Sulfuric Acid 2oz

Taylor R-0009-C-12 Sulfuric Acid .12N 2 oz. Taylor formulates its reagents to remain effective for at least one year, with only very few exceptions (molybdenum indicator in liquid form is one; after four months old it should be tested against a standard periodically). As a general precaution, replace all reagents more than one year old, or at the beginning of a new testing season.
