To determine the cations and anions in toothpaste, you can perform tests such as flame tests for cations like sodium and potassium, and precipitation tests for anions like chloride and fluoride. These tests involve adding specific reagents to the toothpaste solution and observing the characteristic colors or precipitates that form. Additionally, instrumental techniques like ion chromatography or atomic absorption spectroscopy can be used for more accurate quantification of cations and anions present.
Anions have supplementary electrons.
In MgBr2, there are two bromide anions (Br-) for each magnesium cation (Mg2+), so the total number of anions in MgBr2 is 2.
Generally anions. (e.g. Cl-, F-, O2-, N3-)
An aqueous solution is brine; but aqueous solutions are not attracted by anions.

Anions do not play a role in the color of a flame in a flame test because they are not visible as the energy gap do not correspond to that of a visible photon. Flame tests are only applicable to cations.
Anions have supplementary electrons.
The ions are b, anions and cations. Note that xenon is not an ion, it is a noble gas.
The total charge of two nitrogen anions is -2. Nitrogen typically forms anions with a charge of -3, so two nitrogen anions would have a total charge of -6.
In MgBr2, there are two bromide anions (Br-) for each magnesium cation (Mg2+), so the total number of anions in MgBr2 is 2.
Yes. Anions are negative ions and cations are positive ions.
Oxide ions are anions. Anions are negatively charged ions that have gained electrons, while cations are positively charged ions that have lost electrons. Oxide ions have a charge of -2.
An aqueous solution is brine; but aqueous solutions are not attracted by anions.
Generally anions. (e.g. Cl-, F-, O2-, N3-)
Yes, anions have a larger radius compared to cations.
Anions in aqueous solutions can be determined using various analytical techniques such as ion chromatography, titration, and gravimetric analysis. The choice of method depends on factors like the concentration and type of anions present. These techniques involve chemical reactions with specific reagents to identify and quantify the anions present in the solution.
