In the 1:1 complex, alkali or earth alkaline metal ions compete sterically with the dye. They can bind to the rim of cucurbit[7]uril, displace thioflavin T, and thus stimulate its release through ...

Zinc oxide is insoluble in water. State and explain whether zinc oxide is a base, an alkali, or both. Zinc oxide is a base, because it reacts with an acid to form a salt and water. It is not an ...

Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit ...

When the alkali metals are cut, they initially appear shiny grey but quickly become dull and white as they react with oxygen in the air. This is known as tarnishing. Sodium tarnishes more quickly ...
