Cations in a sentence

The arrangement of the original intercalated cations was changed from a single cations A to diverse cations A+A￠, wherein A' represents abundant achiral cations.

It has a spinel -like structure similar to magnetite but uses one quadravalent and two divalent cations M 2 +2 M +4 O 4 instead of two trivalent and one divalent cations.

Zundel cation Two other well-known structures are the Zundel cations and Eigen cations.

Alkenes bound to metal cations are reactive toward nucleophiles whereas alkenes normally are not.

Although positively charged cations always move towards the cathode (hence their name) and negatively charged anions move away from it, cathode polarity depends on the device type, and can even vary according to the operating mode.

Any heavy metal ion (such as copper cations in copper(II) sulfate ) can act as a noncompetitive inhibitor of catalase.

At high pH the glass electrode may be affected by "alkaline error", because the electrode becomes sensitive to the concentration of cations such as Na + and K + in the solution.

Baes, C.F.; Mesmer, R.E. The Hydrolysis of Cations, (1976), Wiley, New York Ions with low charges, such as Na + are very weak acids with almost imperceptible hydrolysis.

Because of its large size, Cs + usually adopts coordination numbers greater than 6, the number typical for the smaller alkali metal cations.

Carbon-localized free radicals and cations are both highly unstable and undergo processes of chain rearrangement, C–C scission in position beta (i.

Consequently, it forms complexes even with alkali metal cations.

Freed cations can be made available to plants but are also prone to be leached from the soil, possibly making the soil less fertile.

Germanium impurities tend to trap electrons created during irradiation; the alkali metal cations then migrate towards the negatively charged center and form a stabilizing complex.

However, some channels may be permeable to the passage of more than one type of ion, typically sharing a common charge: positive ( cations ) or negative ( anions ).

Hydrogen H + is exchanged for other cations, and carbonate (HCO 3 − ) and hydroxide (OH − ) anions are exchanged for nutrient anions.

If an electrical potential (voltage) is applied to such a solution, the cations of the solution are drawn to the electrode that has an abundance of electrons, while the anions are drawn to the electrode that has a deficit of electrons.

In stark contrast, corresponding methylammonium cations always utilize all the available protons for donor NH–OH 2 bonding.

In these compounds one or more hydroxide groups can dissociate with the liberation of hydrogen cations as in a standard Brønsted–Lowry acid.

It may be described as the sharing of free electrons among a lattice of positively charged ions ( cations ).

Like iron but unlike osmium, ruthenium can form aqueous cations in its lower oxidation states of +2 and +3.
