Ammonium Hydroxide → Zirconium

Participants

Reaction Steps

A 1 liter aqueous concentrate was prepared by dissolving 81.2 grams of commercially available dry zirconium glycolate in 500 ml. of 1 molar ammonium hydroxide solution at ambient temperature. Water was added so that the total volume of the concentrated solution was 1 liter. A diammonium zirconium glycolate concentrated solution had been formed with a zirconium concentration of 30 grams/liter, measured as ZrO2. The aqueous concentrate was added to water, at the rate of 10 ml. per liter of water, producing an aqueous zirconium rinse solution consisting of ammonium zirconium glycolate having a zirconium concentration of 0.3 grams/liter, measured as ZrO2. The pH of this zirconium rinse solution was measured at 4.9.
