Answer:

Ion-dipole attraction and solvation of the ions

Step-by-step explanation:

Assume you have an ionic compound MX.

Ion-dipole interactions:

Water is a highly polar molecule.

The partially negative O atom is strongly attracted to the M⁺ cations at the surface of the solid. The partially positive H atoms are strongly attracted to the X⁻ ions.

If the water molecules hit the surface of the solid with the right orientation, the ion-dipole attractions will help dislodge the ions from the surface.

Solvation:

Once the ions are in solution, the ions are stabilized by solvation. The strong ion-dipole attractions cause a shell of water ions to form around the ionss.

Pls help! Polonium has a large, unstable nucleus. Through which process is it most likely to become stable?

Stella [2.4K]

The process through which Polonium is most likely to become stable is: B. alpha decay.

An unstable element refers to a chemical element that lose particles because its nucleus contain an excess of internal energy (neutron or proton).

This ultimately implies that, an unstable element is radioactive in nature.

In Science, some examples of an unstable element are:

Tritium.

Bismuth-209 .

Xenon.

Polonium.

Polonium is a chemical element with a large, unstable nucleus.

Basically, the most stable isotope of Polonium is Polonium-209, which typically undergoes an alpha decay to form lead-205 and the emission of an alpha particle.

⇒ $^{209}_{84}Po$ ----> $^{205}_{82}Pb \;+\; ^{4}_{2}\alpha$

In conclusion, we can deduce from the above chemical equation that Polonium is most likely to become stable through an alpha decay.

The Cabbage Indicator

Masja [62]

.A solution that serves as a pH indicator may be made using red cabbage, which is frequently available in homes. In essence, the color of the cabbage depends on the acidity of the solution and a pigment molecule called flavin or anthocyanin.

To determine whether a material is an acid or a base, red cabbage indicator is a purple-colored solution

Vinegar is an acid and its pH value is less than 7 and hence

Red color is produced

Baking soda is base and its pH value is greater than 7 and between 8-9

and the color produced is sky blue

Bleach is the green which is also a basic and because the pH value is 10-11

Householder cleaner is having pH 11-13 which is basic and hence the yellow is the color of household cleaner .

A basic solution goes away from being basic and toward the center of the pH scale when an acid is introduced. The base is "neutralized" in this manner.
