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 ...

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 ...

Similarly, when an alkali is diluted with water the concentration of OH-ions decreases. This causes the pH of the alkali to fall towards 7, making the solution less alkaline as more water is added.

During neutralisation the H + ion from the acid joins with the OH-ion from the alkali. This is why water is formed in these reactions. \(H_{}^ + + OH_{}^ - \to H_2^{}O\) This is true for all ...
