Boron test kit

The Hanna HI 38074 test kit can determine boron concentration in irrigation waters by direct titration of boric acid.

Boric acid/borate react with chemical compounds containing multiple hydroxyls groups (polyols) such as mannitol, generating anionic complexes at the neutral pH of water.

In aqueous environments boron is mainly present as boric acid, which is mostly un-dissociated. This is why a minimal boron concentration is required in the irrigation water for metabolic activities of the crops. However, excess boron is harmful to plant growth. Boron in excess of 2.0 mg/L in irrigation water is detrimental to many plants, but some plants may even be affected adversely by concentrations lower than 1.0 mg/L.

Kit supplied with
Reagent for 100 tests, HI 98103 Checker pocket pH meter, pH 4.01 (1 sachet), pH 7.01 (1 sachet), screwdriver, 120ml bottle with cap, 50ml calibrated vessel and 2 plastic pipettes
