Just so, is nibr2 soluble in water?

Deliquescent. Soluble in water. NICKEL BROMIDE is a yellow, crystalline material, mildly toxic, carcinogenic. On contact with strong acids or acid fumes it produces highly toxic and corrosive hydrogen bromide gas.

Is nickel hydroxide a base?

About Nickel Hydroxide Hydroxide, the OH anion composed of an oxygen atom bonded to a hydrogen atom, is commonly present in nature and is one of the most widely studied molecules in physical chemistry. Hydroxide compounds have diverse properties and uses, from base catalysis to detection of carbon dioxide.
