The pH of a solution is 6.5 What are the [H+] and [OH ] of ...

 · The uranium-adsorbing abilities of seven plant wastes were investigated. High abilities to adsorb uranium from non-saline water 10 mg dm −3 of uranium were observed with a number of plant wastes tested. However, with seawater supplemented with 10 mg dm −3 of uranium, similar results were found only with chestnut residues. When the plant wastes were immobilized with
