According to one article, "not much was known about which selenium compounds to approve for use in animal feeds when the decisions were made back in the 1970s .. At the time the regulatory action was taken, only the inorganic selenium salts (sodium selenite and sodium selenate) were available at a cost permitting their use in animal feed. This work was supported by the Suh Kyungbae Foundation (SUHF) Young Investigator Award to D.K. Burette stands and clamps are designed to prevent crushing of the burette by over-tightening, which may happen if standard jaw clamps are used. Refill the burette to the zero mark. In order to tell when the sodium hydroxide has completely reacted with all of the hydrochloric acid, we just need to monitor the pH.
